O-Cards?

[reggavegga]

I am confused usually the blocks have something on them already are you saying they had some that are plain and you put that card on it?

It holds the cards inside of it. It comes as a clear block that you slide pop cards into. The cards are sandwiched by the block. I print images i find online onto blank notecards, then pop them in.
