KAIS

KAIS is a slider and cap maker that first appears in the TRB knowledge base in 2022. Its best known families are the POPO, a compact slider built out across an unusually long run of colorways and materials, and the Lucky Candy, whose crystal and ice themed finishes made it a collector favorite.

KAIS works mostly in titanium and zirconium and treats color as a headline feature, which is why a single family can carry dozens of variants. The house sits at an accessible tier, and its pieces turn over steadily on the secondary market, making it a common entry point for collectors building toward the form.
