Loud Lock Mylar Bags Smell Proof 1/4 Ounce All Black - 1000 Count 6.7" X 4" 6mill Thickness - Packaging Bags - Mylar Bags For Food Storage - Resealable Bags - Smell Proof Bags - Dispensary Packaging

Thick mylar, very high quality zipper seal. Black/clear has a nice glossy black finish on the label side and thick clear on the other, entire side is clear not a window. Very nice, will buy again.

Always the perfect packaging no matter the size. Like that these ones have a clear side and have child safety warning on the side.

This product is exactly what it’s described to be and functions perfectly for the products.

These are real good quality. Zero issueswith these bags. Top notch! I will be ordering more!

I love these bags!!! I own a pastry company and these are amazing!

Nice quality good bags

Exactly what we were looking for.

*UPDATE* Dec 6th 2019Some of them didn't do what they were suppose to do. Some of the zipper strips wouldn't line up to seal correctly. Some sealed, and a lot were already zipped closed for some reason but then the zipper part pulled away from the package when trying to open some of them, making it impossible to reseal. I love these bags but idk if I'll ever buy 1000 at one time again. All together I tossed, and/or could not use for intended purpose about 1/4-1/3 of them.. Approx 20%-25% of the order. I don't expect 100% perfection but that was like $25 worth of bags that were defected/unusable. I don't know how customer service is because the window closed for me to do anything and I didn't want to make that big of a deal about it now, but I still figured I would update my experience in review. The rest of the bags were perfect though. I'm only docking one star from my original 5 for the sub par QC.They're still among the best bags! I just hope the quality is a little more consistent next time if I end up getting more.*original review*They do what they’re suppose to! :)
