These pockets are made of heavy duty plastic and seem to hold up nice. the zipper is just like those sip-lock bags that have the little tab that moves back and forth.
I bought some Kaisercraft clear stamps - which they package in one of these pockets - this brought me to looking up their storage products and I found their notebooks and empty pockets.
I feel like these have been the perfect answer to my clear stamp organization issues. The MEDIUM size fit the Inkadinkado sets or two of the american crafts small sets of stamps perfectly. But these LARGE (7" x 9.5") pockets are are great for the bigger ones, or to put multiple small sets.
The only reason I gave it four stars was because I'm afraid the little zipper tab might come off, but sp far, they're holding up!
What a great product!!
This item works so well for storing a variety of things such as Spellbinder Dies, clear stamps and scraps of cardstock. These are useful for storing those little items that are always getting lost in other packages.
Just love the other sizes too.
I found that using the zip lock pockets to store my unmounted stamps works great for keeping them organized and easy to
transport while traveling
I use these to store my Nestie's. One Kaisercraft binder holds 14 or so of these pockets. I put a magnetic sheet in each one and place my Nestabilites on the magnetic sheet inside the folder pocket.
