Not what I was expecting
These are flimsy pouches but they are made of a pretty thick plastic. The zipper is a small plastic piece that is difficult to slide open. I was planning to use these to store paper ephemera packs in them - I was looking for a cheaper alternative to the Becky Higgins Project Life pocket envelopes 6x8 - but unless I slide in a piece of chipboard, these won't work. They are too floppy to store paper ephemera as is without risk of the pieces getting bent.
