Thanks! They are from www.clearbags.com and they are the 1 7/8 by 7 1/16 bags. They fit in there just perfect and don't slide around at all. The shipping is pretty expensive so I always go in with a few people when I order. I also got the cupcake bags (see my blog) and m&m bags on their site as well.
I love this idea, too! I've purchased from clearbags.com previously. I can't find this size bag on their website. Do you have an item #? These would be great for Halloween!
