Canvas Corp Mini White Paper Bags for Artist Trading Cards 25/pk. These cute little white paper bags are great for ATCs. You can stamp and distress them with ink to match all of your ATCs. I even decorate the envelopes with embellishments too. Please know that you can't fold the top down over your ATC; it will stick out of the envelope about a 1/4 inch. These are definitely for your slim ATCs that don't have embellishments on them. It's a pretty tight fit, so leave these for your thinner ATCs. There are 25 little kraft brown paper bags per package and they measure 2 9/16 in. x 4 in.
