SEMINI Double Cap Leather Rivets 400-Set 9x10mm — 4-Colour Kit with 3 Setting Tools

SEMINI 400 Sets Double Cap Leather Rivets is a complete kit of 9x10mm tubular metal studs and matching setting tools designed to secure and decorate leather and fabric projects quickly and reliably.

If you work with leather, denim or soft textiles, having a reliable batch of double cap rivets and the right tools saves time and keeps repairs and decorations neat. This kit includes 400 two-piece rivets in four mixed finishes and three practical setting tools so you can punch, position and set studs without needing separate professional equipment. The double cap design gives a finished look on both sides of the material while the 9mm cap and 10mm post sizes suit projects with material thickness up to about 10mm.

How sturdy are these rivets for everyday wear?

The SEMINI double cap rivets are solid tubular metal studs made to hold layers of fabric and thinner leather tightly after installation. Nickel-free and corrosion-resistant, they are designed to resist fading and tarnish from regular use.

• Solid tubular metal construction for strong holding power
• Nickel-free, anti-corrosion finish for longer appearance life
• Double cap design gives added clamp strength across material layers
• Suitable for items that face regular friction like bags and belts

What materials and thicknesses can I use these rivets on?

These rivets work best on thin to medium leathers, denim, canvas and other soft craft textiles. The post length and cap size are designed so total material thickness should not exceed roughly 10mm for a flush, secure fit.

• Compatible with thin leather, cloth, canvas and soft craft materials
• Recommended maximum combined thickness: about 10mm
• Not suited for very thick or stiff multi-layer industrial leather without trimming
• Double cap covers holes and gives neat finish on both sides

What tools are included and how easy is installation?

The kit comes with three practical setting tools — a punch for creating holes, an anvil for supporting the rivet, and a setter to secure the cap and post together. The included tools let hobbyists and small-shop users install rivets without seeking extra machinery, and basic technique is quick to learn.

• Punch tool for clean, centered holes in fabric or leather
• Anvil provides stable backing during setting for even pressure
• Setter aligns and fixes cap and post cleanly in place
• Clear kit contents allow faster work for batch projects or repairs

Which finishes and quantities are included in the pack?

The set contains 400 double cap rivets in four mixed colours to match common DIY styles and repairs. Having multiple finishes in one kit helps you coordinate with different materials without buying separate packs.

• 400 total rivets, grouped across four mixed finishes
• Double cap (9mm cap & 10mm post) for a polished two-sided look
• Bulk quantity suitable for multiple projects or stock for small shops
• Packaged with tools to start work immediately
