PVC
PVC, or polyvinyl chloride, is a plastic with flexible and rigid formulations. EDC examples use it in surface decoration and stickers; glow descriptions do not disclose additives, thickness or measured afterglow performance.

From colourful inlays to everyday stickers
The same PVC label appears in a custom finish for a titanium-alloy fidget and in flat stickers supplied with a patch set. The material name is shared; the product form and scope of use are different.
PVC stands for polyvinyl chloride. Different formulations can produce flexible or rigid items. Descriptions such as matte, iridescent or glow-in-the-dark still need to be read alongside the material and the specific configuration.
TIDESHARK's Ice Snake finish lists glow-in-the-dark PVC and PET inlays; the main body remains titanium alloy. This photograph shows its daylight appearance.
Ice Snake: PVC and PET in the surface
SEKI's January 2026 introduction to Fengren 1.1 collects custom treatments by several makers. TIDESHARK's Ice Snake scheme lists ice-patterned glow-in-the-dark PVC, plus glow-in-the-dark PET inlays. The same article separately identifies the titanium-snake Fengren body as titanium alloy.
The two photographed sides show purple, blue and pale-green scale areas, with the SEKI mark retained on the reverse. These coloured inlays distinguish this custom finish; they do not make the complete fidget a PVC-bodied product.
The description does not map each PET and PVC region or disclose luminous additives, thicknesses or proportions. A daylight photograph is not a brightness or afterglow-duration test, and the ice-pattern process description does not supply a complete manufacturing specification.
CHAOS: look for the flat stickers
The CHAOS set's raised patches and flat stickers share the frame. The original description specifically assigns matte PVC to the supplied stickers, not automatically to the raised patches.
In its November 2024 CHAOS introduction, MTAK first describes raised relief, a matte texture and 3 × 3 cm square patches, then introduces matching stickers supplied with the set. It is this second item that is described as matte PVC.
The photograph puts both forms together: the raised patches sit above flat coloured designs on a backing sheet. It shows how the same pattern becomes two different accessories—and why appearing in one picture or one set does not establish a shared material.
The listed set contains nine square patches, one loop-fabric backing panel and one nine-square sticker sheet. PVC is recorded here for the included stickers; the adhesive, coating formulation and composition of the patch bodies are not specified.
Iridescent PVC: material plus surface effect
A separate November 2025 product roundup lists iridescent PVC among the materials and effects used in handmade decorative faceplates. The list also includes imitation-shell paper and several decorative or colour-changing effects. It does not provide a single formulation shared by every faceplate.
A material name is not a surface specification
The British Plastics Federation explains that additives affect PVC products and that plasticisers can make PVC flexible. This explains how PVC can serve different product forms, but does not identify any particular additive in the examples here.
Matte describes the stickers' surface, while glow-in-the-dark belongs to the specific Ice Snake inlay scheme. Neither follows from the letters PVC alone. Wear, fading, adhesive life and cleaning requirements need product-specific instructions or tests.
The Fengren article also covers other makers' treatments, whose care instructions cannot simply be transferred to Ice Snake. When identifying or replacing a decorative part, its maker, compatible edition and exact finish are more useful than the PVC label alone.

Examples in detail
SEKI · Fengren 1.1
TIDESHARK / Ice Snake custom finish
PVC and PET glow-in-the-dark inlays belong to the custom surface scheme; the titanium-alloy body is recorded separately.
The polymers are not assigned by colour, and the daylight image is not a glow test.
MTAK · CHAOS
Nine-square set / included PVC stickers
Matte PVC describes the flat stickers, without establishing the composition of the raised patches in the same image.
The set contains nine patches, one loop-fabric backing panel and one nine-square sticker sheet.
Common confusions
From Iridescent PVC: material plus surface effect
Iridescence therefore remains an appearance description for that scheme, rather than a separate base material. Nor does the list establish identical PVC use in every design. This text example explains the naming boundary without using an unrelated faceplate photograph as material evidence.
