Sometimes people send me a slot card in a little plastic sleeve. Where do you get these sleeves? I want them so I can separate cards with variations and then put the in my box of traders. This way when people are looking through the box they can see the differences.

I was thinking of packing the boxes that you get at the slot card desk, but they are to long for my suitcase. Today I replaced a ballast in my fixture and the box it came in is the same size but half as long. The cards fit perfect. Barry
