Not at all sure where this belongs or what to call it .
Wife buys these acrylic photo holders and we have several . They are 3/4 thick ( 2 x 3/8 ) and work on magnets .
So I got to thinking ................... if double caps would stick well then I could put some leather on them . Also makes 2 holders out of 1 ( yep , I am border-line genius ) wife just says I'm tight !!
Needs a little heavier weight , this is 4/5 oz , and would work better I think .
