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

Super durable and quality

Perfect! Thick, great size, exactly what I needed.

needed small see-through bags for crafting. these are excellent. more substantial than a ziplock baggie, efficient size. recommended

I bought these to store small LEGO builds form an advent calendar. They are PERFECT! Sturdy and large enough for the legos and small enough to store efficiently. This way I can get rid of the big advent calendar box they came I highly recommend these!

Nice and thick. Perfect for my use. Ive had one in my pocket for medicine for a month and its still holding strong.

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.

The item was as advertised and them some. It was thick and just the right size that I wanted: 4. The opening was easy to open, to unzip, as it were, because the top was off-center. Opening and sealing shut is easy, tight and strong. Quantity and price were good. Like I said, just what I wanted.

These worked well for storing less-worn jewelry. Nice and heavy. Zip seal is strong. Cut edge is offset for easy opening. Only negative is large minimum quantity. But now I have plenty left for other organization tasks.

These are great! Im using them at my wedding for our petal toss bags and they are the perfect size!

Super durable little bags. I get these to pre mix protein and supplement packets. Easier to just grab and go. Perfect size for my needs - it holds a big scoop of protein and an equal amount of powdered supplements with room to spare. Biggest bonus of these bags is the 4mil thickness. Most bags are 2mil, which is just fine, but you can really notice the extra durability of the 4mil. And the price is about the same. I get different sized bags from my local food service store for much cheaper, but they don’t have this size available. Still good for the price.
