I am in love!!! Makes my ebay selling soooo much easier. I was purchasing those thin yellow envelopes at Dollar Stores for $1 and you get 4. So like .25 each. These are much more cost effective and a LOT more durable and I can fit more things in them per square inch. They may be smaller than those legal size yellow paper envelopes you get 4 or 5 to a pack but they expand so i can ship more variety of items. I have fit 2-3 shirts, toys like Barbie in a box, bunch of party supplies like 2 tablecloths 2 packages of large napkins and still room for more, Coach small purses. No ripping or stressing of envelope. I will be back buying more in bulk in about 2 weeks or less. Just wanted to try out a smaller amount. Makes ebay selling so much easier. Along with the labels I bought to print addresses on my packaging for shipment time is cut almost 75%. No more taping envelope flaps or taping where product stresses paper envelope and rips. These have not ripped on me. The only thing I don't like is the plastic piece you tear off to seal the envelope sticks to your hand and hard to detach. You have to shake it off because if you pull it off with other hand it sticks to that one. :-) I save too much money and time as well as able to fit more items in these per square inch of what I was using I don't care love them.
