Review on Collecting Warehouse Plastic Reclosable Zipper by Peter Whitney

These bags have a good thickness and such, but when you try to open them, the clasp is too tight. In fact, on many bags, tearing it open will cause the top of the seal to come loose. If you spread the top and stick a nail in between to pry it open, you literally won't be able to open some packages. I've bought many different styles, but opening a bag has never been more difficult than this one. I may have gotten a bad batch but I wouldn't risk my money ordering again to get the same ones I got the first time.
