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

Good quality

They are the perfect size! They will tear on the sides so be careful opening them too wide. But, then what doesnt. Not the companys fault Im using them to store small pieces of paper for elementary students!

We use these to hold parts that we ship. Theyre good for keeping multiple items together, and even if its only one item, we think it gives a professional look to our customers. We previously purchased them from a major chain store, but the last batch we bought split on the sides, so we returned them. We were delighted to find these.

I bought these for real estate - to put in face masks.

If you have something 4 exactly, it will not fit in here. Bought these to protect some unusual sized card stock in a game of mine which are 4x4 But couldnt fit it because the bag is exactly the size it says, so when opening it to fit the card in, they do not fit. Cant knock the builder/seller for being honest, just didnt meet my needs as i needed at least a couple more millimeters of room to fit. But Ill use them for other games Im sure.

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.

Bags are advertised and study. They are just what I needed for my application.

Love these! They are very durable and the right size.

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.

The bags arrived on time and well packaged. I really like the thickness and the fact that the top is slightly offset so opening is much easier.
