I don't know what to say about these.  They are indeed thank you "t-shirt" bags and they did come in a cardboard box!  They arrived quickly and were the cheapest I had found to date. I didn't bother to count them to see if the count was right! LOL!

Update: A fellow vendor needed bags and borrowed some of these.  Apparently this are a good deal heavier than some of the real economy thank you bags.
