Review on 200-Pack 3" X 3" Clear Plastic Reclosable Zip Bags | Heavy Duty 4 Mil Thick Poly Baggies With Resealable Lock For Travel, Storage, Packaging & Shipping by Seth Hogate

I absolutely love how much better these bags are versus 2mil for my spare diamond painting drill storage.The only reason I did not leave 5 stars was due to a couple of the bundles (they are bundled into 10 bags of 100 each) being slightly defective. They were still completely usable, but the flaps at the top were cut a bit short on nearly 200 of the bags I've used. I still have 3 unopened and 1 partial left, so I don't know if more will have issues. After sitting for over 6 hours opening bag after bag after bag, I found that my fingers hurt a lot trying to pull the zips (they are harder to open, which I attribute to the thickness of the bags, not a problem in their quality) so having some of the bags with really short flaps to pull on made them tougher to open. Otherwise, I absolutely love them.Initially, I tried looking for slightly larger bags in CM (6x8cm is just a tad larger than 2x3in, however it is hard to find zip bags in metric sizing in the US) but these are actually a tad wider than 2 inches, whereas the 2mil bags I replaced with these were dead on 2inches. I was pleasantly surprised. I don't know how much extra space they gave me being a couple MM wider since the thickness prevents them from holding as much as their 2mil counterpart, but the rigidity makes the switch completely worth it. The 2 mil either sagged and would slip under other bags or weren't strong enough to push all the way down into the boxes I keep them in, so they looked very untidy. The 4mil bags immediately improved the aesthetic of my storage boxes and I'm glad I made the upgrade. Highly recommend. My only regret is not buying these from the very beginning!
