Does anyone display or store their strikes in those black "velvet" display cards? They hold an airtite about 53 mm in diameter. I'm currently storing mine in the cards, in a plastic storage box. My question--are there display cards that will hold a strike in it's original case? I want to keep my blue and pink-cap strikes in their original cases, but store them in the same manner. How do YOU store/display your colored-cap strikes? Thanks in advance.
