Very clear & thick vinyl. But, things must be curved a little in order to get into bag. Bag is barely wide enough & tall enough. The zip takes up space at the opening. Not a good fit for Craft Your Life kit, or the big stamp sets that have the trifold cardstock user guide. Upon arrival, the openings were all dented where the zipper is, but didn't crack. I will not order more.

Great quality! Nice size.

I am finding that a number of my die sets and stamps fit nicely into these envelopes. The cardboard backing on some has gotten a little trim so it will fit because of the zipper closure, but all is well. These will go into a plastic open container and I will have easier access that my previous attempt at organization. I will need more!

I first got these as part of a combo pack of the two sizes and needed more of the larger ones. I cut the zipper bit off and use these to store my larger stamp sets along with any matching dies and/or stencils. the material is thick and high quality so even though its a bit of a tight fit to have the dies and stencils in the bag with the stamps, I am not concerned with the sides of the bag splitting. (and in case you're curious, if you want to store your stamps in the bag without removing the zip, you can pull the plastic closing mechanism off to slide the backing sheet from the stamp set in and then put it back on without damaging the bag.)

I really like how these envelopes help to keep all elements of stamp kits together. Thank you, Altenew!
