Plymor6" x 9" (Pack of 100), 4 Mil Heavy Duty Zipper Reclosable Plastic Bags

I love these bags, I use these to keep my liquid toiletries and my travel watercolor palette stored in case of a leak during travel. They're also great for storing my Signature Needle Arts knitting needles and I also use them in my art studio. I've recently found that they also work great for storing stamp pads and acrylic and rubber cling stamp sets. The 4mm plastic is nice and thick so it keeps my pigment/dye ink pads from drying out too quickly and they're a much more permanent and sturdy alternative to keeping your cling- stamp sets in the flimsy retail plastic packaging they're sold in. Just cut about 1" off the bottom of the stamp sets cardstock backing so it fits in the bag, but keep the cardstock backing, it gives the acetate sheets holding the stamps a little more support.

These bags a great quality, actually better than I expected. They seal completely airtight, thick material and really tough.These are probably overkill unless you need bags for items weighing over 5lbs.

They are the perfect size—not too small and not too big. Able to comfortably hold a 3-panel pamphlet and zip snugly. Looks very professional.

We are reusing the bags on a repeated basis. They are very durable and hold up to our daily use.

I've ordered 4 mil ziplock bags multiple times in various sizes from Collecting Warehouse. Their bags have a really heavy duty zipper that's easy to make sure is zipped closed, and my customers often comment on the nice quality of the bags that my products are packaged in.

I use these bags to hold thousands of loose rounds of ammunition. They are Boogaloo certified by me. Look it up on your own. I think the 4 mil thickness is perfect because it's strong enough to hold this heavy amount of material and retain its flexibility, unlike 6 mil bags which are very rigid. And it's at an ideal price point. Highly recommended.

These bags are great for holding standard-size sewing patterns (Butterick, McCalls, Simplicity). The larger ones (Vogue & some costume patterns) must be folded a little to get them to fit. I docked a star because the bags are a little hard to open the first time. The zip seal is pretty tight, and it's easy to tear the top above the zipper.A note on the picture: I punched the holes to help them compress better when I put my patterns in their storage case. The bags did NOT have holes in them when they arrived.My only other problem with this order has nothing to do with the product itself. Amazon shipped the bundle of bags in one of their shrink-wrapped packages, which (of course) requires melting the plastic shrink packaging using heat. Umm... Hello? Amazon? YOU MELT THE PRODUCT PACKAGING THEM THIS WAY. Fortunately for me, only the bag containing the bags was melted beyond use. The bags themselves are fine, so I just relocated them to a larger ziplock for storage.

Happy with product, thank you.
