Canvas Corp. Mini Kraft Brown Paper Bags for Artist Trading Cards. These cute little kraft brown paper bags are great for ATCs. You can stamp and distress the envelopes 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.
