These are not at all as thick as they claim to be. Definitely not 3.15 mil, not even 2 mil. The only reason I’m not returning them is because I need them immediately and don’t have time to wait for a new shipment. Be aware, you’re basically buying thin sandwich bags.

rip a few opening the bags

Was not the right size nor the right thickness as advertised complete trash not worth the money don’t buy scam completely

Too thin for my original purpose

We needed small bags for frozen rodents for our pet snakes (they typically come in bulk packaging or vacuum packed). These work for 1 mouse per bag easily. We also use these for board game parts and bits. Not much else to say here - they are good quality bags in a large bulk quantity.

One of the bullet points in the About this item section of the listing says these are 3.15 mil thick. Im not sure why 3.15 and not 3mil but whatever... these arent anywhere close to that! I usually buy 1,000 qty 2mil thick 4x6 poly bags on Amazon but ended up coming across this listing. Same quantity and thicker bags for a couple dollars cheaper than the bags I usually buy? Heck yeah, why not right? Well, the only thing good about these bags as that you save a couple dollars but it ends there. These bags are so much thinner than the usual 2 mil bags I buy. I mean... its NOTICEABLY thinner. Then theres the fact the bags vary in sizes -- MOST are not 4x6. They vary in sizes with most being slightly larger than 4 x , some smaller, some bigger. The real kicker is that a bunch of the bags are not perfectly rectangular... some are so bad looking, I cant explain how bad the quality control is. Im including a photo of what I mean.... The fact that the corner arent square on many of the bags is what compelled me to write this review in the first place. Moreover, the bags are noticeably more wrinkly than the usual 2mi 4x6 poly bags I buy probably because theyre so thin. I would not recommend these bags for anything other than a few small pieces of paper but seriously, spend the extra couple dollars for quality 2 mil bags.

These bags are very thin.

If you are looking for 2mil or thicker bags then these are not for you because they are too thin maybe 1mil or less, for what I need them they are ok, I use them for bagging small jewelry boxes in my business to protect them from dust and humidity during shipping.

Only one mil thick Flimsy and worthless.

Just what I needed for a large project. Sometimes a bit difficult to open the bag yet very secure after.
