Where do you get the CD cases for your acrylic stamps? I know you can buy them at Wal-Mart, but do they have to be a specific size? Do you have to take out the little "tray" that the CD sits in? If so, the ones that are sold at Wal-Mart, are you able to take the tray out?
I bought mine at Walmart. Just make sure they are the thick ones, not the slim style. To pop ou the middle, I have found that the best way is to take one of the outside corner and pull it back somewhat. It kinda feels like you are breaking the case but you're really not. It then just pops out.
I got mine from staples. You can get a pretty good deal on them. Make sure to get the regular cases and the cd tray pops right out. I also use the cd cases for my spellbinders dies, which is really nice.
