100PCS PVC Rubber Pin Backs, Lapel Enamel Pin Backs for Brooch Tie Hat Badge Uniform Backpacks, Rubber Pin Backs for Enamel Pins & Rubber PVC Pin Locks for Enamel Pins (Black)

The back pin holder looks like it should work well. I have a couple in use in my hat and so far they are holding and I’m not getting poked by the pins so that is good but time will tell

We are forever losing the backings on the pins that we get so we figured we would get this large pack to keep up. These backs fit SO snugly that I don't think we will be losing anymore any time soon. They fit great and are comfortable even when they rub against skin. Great price as well.

These pin backs are exactly what I needed for my enamel pins. They hold securely, so I don’t have to worry about my pins falling off. The rubber material feels strong, and they’re much easier to put on and take off compared to metal clasps.
