DZ Top-B:
The Mechanical Fidget Slider Series Guide

The DZ Top-B is a mechanical fidget slider and the founding model of DZ’s TOP series. A guide to the Bubble, Rain and VIP slider editions, their production runs, materials, the rail-and-detent mechanism, and what to check buying pre-owned.

The DZ Top-B is the mechanical fidget slider that started DZ’s entire TOP series. If you have been scrolling the secondary market trying to pick one, you already know the problem. There are dozens of versions. The names barely make sense at a glance, Bubble, Rain, Qin, Horseshoe, and half of them look nearly identical in a listing photo. So which one do you actually buy?

Start with the thing nobody tells you up front. Pick up a Top-B and push the plate. It glides clean and lands on a crisp click, and there is not a single magnet inside. A metal slider this smooth almost always rides on magnets. The Top-B does not. The plate runs a machined track and a small PEEK detent sets the resistance and the click, so the feel is purely mechanical. That one detail is why a Top-B feels different in hand from the magnetic sliders most people start with, and it is the one thing every edition below shares.

So here is the plan. First the quick answer on what the Top-B is and how the action works. Then the part that untangles the catalog, because almost every Top-B belongs to one of three families, and once you see them the dozens of editions stop looking random. Then the full edition table with runs, years and materials, what to check before you buy pre-owned, and a straight call on which one is right for you. If a coin is what you actually want, that is a different model, the Top-C.

The DZ Top-B is a mechanical fidget slider made by DZ (Metal Toys Dz), and it is the model that launched the brand’s TOP series. A fidget slider is a palm-sized metal bar whose top plate rides a machined guide track, with a mechanical detent setting the resistance and a crisp click at each end. You hold it, you push, it snaps, repeat. That simple loop is why sliders became the quiet, pocketable answer to the fidget spinner for adults who want real machined feel.

The Top-B started this whole line in 2022 with the Bubble slider, and the slider form carried through the Rain line and the annual VIP editions. Every edition in this guide shares that same slider mechanism, from the Bubble and Rain lines to the themed and VIP drops. DZ’s dedicated haptic coin is a separate model, the Top-C.

So how do you make sense of dozens of editions with names like Bubble, Rain and Qin? You group them. Almost every Top-B belongs to one of three families, and the colors here carry straight down into the table below.

Launched 2022. A bubble-textured face in runs of about 100 per material, from cupronickel and zirconium to a Corian-and-PEEK build, with an exotic titanium-damascus Mokuti later. The piece that defined the Top-B feel. Best for the purist who wants where it all began.

Followed in 2024 with a rain-pattern face and a deeper material range. Titanium is the regular edition, the Zircuti was a 998-piece limited, and it also appears in zirconium, steel and brass. The most circulated Top-B on the secondary market. Best for the easiest one to actually find and carry.

DZ’s annual collector editions. The 2023 Qin in copper, the 2026 Horseshoe pairing steel and zirconium with red rosewood, cherry and black walnut, limited to 139. The hardest Top-B sliders to find. Best for the collector chasing the trophy.

Everything else, the themed drops, glow-resin specials and one-off materials, is built on the same action and sits in and around these three. In the table below they stay neutral, with the three families color-coded.

So if it stays this smooth without a single magnet, what is making the click? Strip away the finishes and the Top-B is one mechanism done well, and an unusual one. The top plate rides a machined mechanical track, and the resistance and the click come from a PEEK detent plate, not from magnets. That is the key thing that sets the Top-B apart from magnet-based sliders: the action is purely mechanical, rail and detent rather than magnetic attraction. Push the plate end to end and it runs along the track, then resolves into a clean, audible click rather than a mushy stop. PEEK is a high-performance engineering polymer, and DZ uses it as the detent and wear surface so the action stays consistent over years of use.

That same action carries across every slider edition, which is why the Bubble, Rain and VIP pieces feel like one family despite the different faces and materials. The variety lives in the texture and the metal, not in the motion: the Top-B slider slides, and that is the point.

The reason people keep a Top-B on the desk is the action. The PEEK detent is tuned for a push that feels smooth all the way through, then resolves into a click that is clean and audible. Material changes the character on top of that: cupronickel and copper feel dense and warm, stainless steel is grounded, titanium lightens everything up, the Corian-and-PEEK build is the lightest, and zirconium and Zircuti sit at the premium end with a hard, slick surface. Mokuti and the VIP wood-and-metal pieces are about the look as much as the feel.

Say you have found one you like, secondhand. What do you actually check before paying? Because the slider runs are small and the VIP editions especially scarce, the Top-B lives mostly on the secondary market. A few things matter when you buy pre-owned.

Confirm the exact edition and material. This is the big one. The Top-B runs to dozens of editions and finishes, some under very similar names, so pin down the precise edition, the material and the run with the seller before you buy. Clear photos of the face art and any engraving help confirm it.

Pin down the edition and material. Top-B alone is not enough. Know whether it is a Bubble, a Rain or a VIP piece, and which material, since that drives both the feel and the value.

Use rarity, not hype, to judge. The VIP editions (Qin, Horseshoe) and the exotic materials (Mokuti, Zircuti) are the hardest to replace. The Bubble and Rain pieces in steel, cupronickel and the Corian build are the more accessible end.

So which Top-B is actually right for you? With one mechanism across the whole line, the choice is not about the action. It comes down to three things: how you will use it, which material you want in hand, and whether you are buying to carry or to collect. The quick version is pick the edition for the look and the material for the feel. Cupronickel, copper and steel for everyday density, titanium for an all-day lightweight carry, zirconium or Zircuti for a premium daily, and the Corian-and-PEEK build for the lightest option. Chasing rarity instead? The VIP editions and the Mokuti are the trophies.

The Top-B launched DZ’s broader TOP series, and the siblings are worth knowing:

Top-C: the compact round model and DZ’s dedicated haptic coin, a tap-and-click pocket disc rather than a slider. Top-D: a larger, more substantial slider than the Top-B. Top-E: a mid-sized slider balancing comfort and footprint. Top-F: the smallest and most pocketable slider in the line. Top-H: a later TOP-series slider, leaning minimalist.

One note for completeness: if a coin is what you are after, DZ’s dedicated one is the separate Top-C. For two more deep dives on sliders in the same family, see our ACEdc Gamer engineering guide and the LAUTIE Choc engineering guide.

For collectors who run more than one Top-B, DZ also makes a matching display stand. It has no mechanism, it is a static base for showing the pieces, but it is the natural companion once a collection grows.

DZ (Metal Toys Dz) is an independent maker, led by Lao Dai, that specializes in mechanical fidget toys. The TOP series is its founding and flagship line, and the Top-B slider is where it started. DZ’s approach is mechanical and material-driven: design a solid action, then iterate on it in premium metals and limited runs rather than chasing disposable novelty. Over time the brand expanded the Top-B across dozens of slider editions and materials, with the Top-C serving as DZ’s dedicated coin in the wider TOP series.

The Top-B slider is where DZ’s TOP series began, and it still rewards collectors because it pairs one well-tuned PEEK-detent action with a tight set of editions in premium materials. The Bubble line is the origin, the Rain line is the most circulated, and the VIP editions are the trophies. That is the whole slider story, and it is worth understanding as a family rather than a single purchase.

If you are new to it, a Bubble or a Rain piece is the cleanest entry. If you are buying pre-owned, pin down the exact edition and material, and use rarity to judge. And if a coin is really what you are after, the Top-C is DZ’s dedicated one. The rest of the TOP lineup, from the Top-D down to the minimalist Top-H, is worth knowing once the Top-B has earned its place in your carry.

One action, dozens of faces. Start with a Rain. Chase a VIP. Let the Mokuti be the one you hunt.
