These brass plated steel rivets have a 15mm stem length and a 9mm cap size.
They are double capped rivets, which means they look good from both sides.
To achieve a strong fix, you need around 2-3mm of your rivet stem to stand proud of the leather layers, before adding the cap and hammering the two halves together, either with or without a rivet fitting tool. (See related items below)
This is a pack of 100 rivets.
