空心鉚釘7.5公釐/3-4公釐補充包銀色25件

The 7.5mm heads sit perfectly flush on my leather projects, and the 25-pack is just the right amount for a few keychains. No rust after a week of humid weather, which is a relief.

The brass surface hasn't tarnished a bit after sitting in my stash for months, which matters when you're making jewelry. They set cleanly through that 3-4mm fabric stack without any buckling, so I've already gone through one pack on a denim repair project.

These rivets set perfectly flush with the material surface, giving a clean look that doesn’t catch on anything. I’ve already used a handful on a 3.5mm leather belt and they held tight without any wobble.
