Review on 🏹 Arrow Fastener WA3 16 Aluminum: The Ultimate Solution for Quick and Efficient Fastening by Dave Hammon

These are aluminum washers with a 3/16" hole for use with 3/16" pop rivets on soft materials such as leather. Rivets are typically used on metal, but with a washer, they can be used to fasten softer materials like plastic or leather. Exactly what I ordered and Arrow is a trusted brand for such products.
