Plymor Heavy Duty Plastic Reclosable Zipper Bags, 4 Mil, 4 x 4 (Pack of 100)

I used it well, for what I bought it for and it was a good price.

These bags are thick however so many of the bags had a hole in the side seem. It’s so annoying! I put glitter in these bags and if I don’t see the hole, there is a glitter explosion every time. I would not purchase again or recommend these. -A girl who is covered head to toe in glitter because of these annoying bags had holes in them.

These bags are perfect if you have a lot of strategy board games. I organize them all with these bags. Not to big or too small, and a heavy gauge/mil. Must have if you have a lot of board game parts.

This product is great to organize all your little items (i.e. necklace, earrings, etc.). I also use it to put snacks in for the little ones. Will order it again.

Thick 4mil plastic resealable 4x4 bags. Quality bags to store jewelry findings in!

Best plastic bags for packaging my Etsy stuff. Ive also used them to organize board game pieces. Highly recommend.

I am of a certain age. I got so sick of having bottles and bottles of pills... most of which I keep around but rarely use. Bought these plastic zipper bags and stuck labels on them all. They are strong enough that they will stand up in a line where 15 of them take up the space that just 2 bottles fit in before. Easy to shuffle through and love it!

Great product for a great price! I use them to package lotion bars, it was exactly what I was looking for!

I purchased these bags from Collecting Warehouse. I use these bags in my workshop for small quantities of hardware parts - nuts, bolts, washers, screws, etc. While I cannot comment on whether these bags are 4 mil, I can state that they are significantly thicker than the name brand zip lock sandwich bag. They are similar in thickness to the zip lock quart size freezer bags. I have no trouble opening or closing the bags as some reviewers have described. Just to be clear, I have VERY large hands, so you would think if there were an issue I would have encountered it. I was impressed with the packaging as well - I purchased a bundle of 500 bags. These came in five 100 bag zip lock bags that were clearly labeled as 100 Bags - 4x4 4Mil. This was very handy as I also ordered some 3x5 bags from the same company (I was equally impressed with those and wrote a similar review). The bags measure right at 4x4 in the usable part of the bag (which excludes the zip lock). You could put a 4x4 paper card into the bag, but it would be difficult and you could not put more than a couple inside before the bag was completely stuffed.

I love these bags. They are nice and strong and they really up the quality of my orders when my jewelry is put into these bags as opposed to the cheaper looking thinner bags. I like my product to look nice and it really does in these nice square bags. I will never use anything else anymore to sell my jewelry in.
