GPI - 5 X 3 100 Count, 2 Mil Clear Reclosable Zip Plastic Poly Bags with Resealable Lock Seal Zipper for Snack, Candy, Nuts, Cookies, Sewing Supplies, Beads.

Very cheaply made

Great for the price and a variety of sizes

Perfect for what I needed them for

The bags are strong and easy to open.

I use these for my scentsy samples!!!

These are bags. I made bread and needed bags. They worked. What else can I say?

The quality was more than I expected

Nothing

Durability and sturdiness? Im guessing on that. They seem well built on first impression. Im not using them over and over. They are for small parts storage, and if I put something into one and write on it with a marker whats in there, I may not take it out for a year or six. But its contained and labeled, which is why I got them. Sufficient to the purpose I need them for they clearly are.

As advertised, not incredibly thick but does the job for packaging.
