RUBYCA 500 Sets 21mm Silver Cat Claw Studs - Bulk Leather Findings

Our review of these RUBYCA cat claw screwback studs finds them best suited for makers who need a large, consistent supply of decorative hardware for leatherwork and punk-style projects. The single biggest reason to buy is the quantity and consistent zinc alloy construction: 500 sets in a zip-bag make it easy to kit multiple projects or stock a small workshop. The studs are silver, 21mm high with a 7mm base, and arrive with slotted screws for straightforward installation, so crafters who value workability and value for money will appreciate this pack.

Key Features

• Pack size: 500 sets provide a plentiful inventory for repeated leather-craft projects or small business use without frequent reordering.
• Material: Top quality zinc alloy metal offers a durable finish that holds its shape and gives projects a professional, metallic look.
• Design: Round base cat claw spikes add a distinctive punk or decorative accent to bags, belts, jackets, shoes and dog collars.
• Fastening: Slotted screwback design makes installation secure and removable, suitable for layered leather and thicker materials.
• Packaging: Comes in a genuine RUBYCA zip-bag so the small parts stay organized and ready to use on the workbench.

Who It's For

This pack is ideal for leathercrafters, hobbyists, costume makers and small makers who need a large number of identical decorative studs. The long run of 500 sets means it is especially useful for projects that require many fasteners, like studded jackets, belts, or producing multiple accessories for sale.

Those who should look elsewhere include buyers who need a single sample, large individual statement spikes, or specialized screw types; this set is focused on quantity, consistent 21mm cat claw studs and slotted screws rather than large or custom hardware.

Pros & Cons

Pros

• High value pack size gives excellent value for money when building multiple pieces or stocking supplies.

Cons
