レザーワッシャー

The 5/8" outside diameter covers my rivet heads perfectly without looking bulky. I've gone through half the pack already reinforcing strap ends on bags and not one has cracked or split.

I used these washers on a couple of belt straps and they sit flush against the hardware without bulging. The 5/8" outside diameter gives just enough reinforcement around the rivet.

The 1/8" hole is punched perfectly centered, which matters when you're setting snaps on a strap and don't want the washer wandering. I've gone through half a pack already on a belt project and they sit flush under the rivet without bulging.
