Review on Uxcell Button Inches Hanging Pictures Crafting in Picture Framing by Gelin Battle

I have to admit I didn't use this in a picture frame, I used this for another application. I built the air filter in my wood shop and used 1/4" thick plywood to attach the filters. Nothing to fix the situation. I thought of hammering in a half inch nail or screw to take the 1/4 inch holding the thick rectangular strip of plywood but reminded me of seeing a lock in one of my wife's photo frames. I ordered it and used it to hold the plywood top in place. Now I can easily remove the holding plywood when it's time to make the Filter to repair or replace Happy for the purchase.
