Jetmore 420 Sets Leather Rivets, 4 Colors and 3 Sizes Leather Rivet Kit with 3pcs Leather Tools, Double Cap Brass Rivets Review (2026)

Who this rivet kit suits

This kit fits a maker who wants a stock of hardware on hand for repeated small projects rather than buying rivets one size at a time for each build, since 420 sets across three sizes and four finishes cover most strap, wallet, and bag hardware needs without a second order. Our score of 8.3 out of 10 reflects strong marks on features and value, with build and materials rated lower at 7 out of 10. It is a good match for someone assembling straps, cardholders, or light bag hardware at a hobby or small batch pace, since the assortment format means less precision inventory planning than buying single size boxes.

Sizes, finishes, and tools explained

The kit includes double cap rivets in three sizes, listed by the seller as 6x6mm, 8x8mm, and 8x12mm, across four finishes described as gold, gunmetal, bronze, and silver. Jetmore's own product description states the rivets are made of nickel free copper, described as anti rust and durable, which differs from the brass material the site listing's marketing copy references elsewhere. Three setting tools ship in the kit alongside the rivets, intended for punching a hole and setting the cap and post together, and everything is organized in a transparent storage box so a specific size and finish can be found without digging through a loose bag of hardware.

Fitting rivets to your leather

Double cap rivets like these work by punching a hole through the leather layers, then pressing the post through the cap and setting it with the included tool until the two halves lock together, a common closure for strap ends, wallet corners, and light bag hardware. The stem length on any double cap rivet limits how many leather layers it can close, so a thick multi layer strap junction may need a longer post than these smaller size options provide. Testing fit on a scrap piece before committing to a finished project is worth the extra minute, since an undersized rivet will not seat cleanly through a thick stack.

How it compares with other rivet kits in this guide

Hotop's 50 piece copper rivet and burr washer kit scores higher in this guide and uses a different washer based construction rather than double cap rivets, which some makers find grips thick leather more securely. Selizo's 480 set kit is nearly identical in format and size range to this Jetmore kit and scores close behind it, while the larger 640 set and 1000 set kits from other sellers trade a bigger quantity for fewer color options or a plain brass only finish. This Jetmore kit sits in the middle of the pack on quantity but keeps the four finish color spread that some of the larger kits drop.

Bottom line

For a maker who wants an assortment of small hardware sizes and finishes ready for straps, wallets, and light bag builds, this Jetmore kit delivers a reasonable spread in one storage box with tools included. Confirm the stem length against your leather stack before ordering if you are working with thick multi layer joints, since the included sizes suit thin to medium stacks best, and keep in mind the rivet material is copper rather than brass when planning for outdoor or heavy wear gear. Anyone who wants a washer backed rivet for maximum hold on heavy leather should look at a burr washer style kit like Hotop's instead.
