APQ Supply Storage Bags with Zipper, Amber 6 x 8 in, 3 Mil LDPE, Reclosable Zip Closure, Opaque Light-Reducing Poly Bags for Storage, Packaging and Shipping, 100 Count

So far so good. The bags arrived packed well for the shipping and my UV applicator sponges fit perfectly in the bags. I was able to label each bag with a sharpie, I haven't had to put anything in the bags that needed protecting from UV light yet but I will soon. So far all is good.

Best bags ever nice and thick

Best price on amazon! Blocks light as intended,Not a complete airtight seal on some bags but can't really complain. Gets the job done in most cases.

I ordered these bags (8” x 8”) for using with clear color mason jars (32 oz) for my Kratky hydroponic gardening since there is a shortage of amber color mason jars during the pandemic. The bags serve to keep light out of the jars which is necessary for this type of gardening. I secured the bag to the jar with a rubber band around the neck of the jar. I can still see through the bag enough to determine if I need to add water. Works out perfectly!

Frustratingly, neither of my wholesale distributors seem to carry anything like this. Thankfully, this Amazon seller does. This is a repeating purchase for us. We often send home liquid medications in small yorker bottles (we're a vet clinic). This bag takes care of light sensitivity and there's enough room to pop in the medicine & dosing syringe. Plus the medication labels stick smoothly to the bag instead of wrapping all wrinkled and unsatisfying on the yorker itself.

These are not light tight at all. I can’t dispute the UV protection rating they give, but given that they advertise useful for shipping photographic film, this is misleading at best and outright lying at worst.As shown in the review photo, these are shockingly clear and I can see my hand through them with even the mildest reflection from the countertop behind it.

I use these bags to store negatives and treated paper for cyanotypes.Good size, good thickness.

I was looking for small plastic bags for disposing of sanitary items. These bags were exactly what I needed. The right size and shape, and easy to open. I'll order them again when I need to.
