Smead Poly Envelope, 1-1/4" Expansion, String-Tie Closure, Top Load, Letter Size, Green, 5 per Pack (89543)

I used these in my little one's baby book for extra storage. They work great! I was able to store a good bit in each one. One is full of cards from my baby shower and another holds her hospital bracelets and lots of other things from when she was born. The baby book is 3 rings a of course this isn't. I didn't have a hole punch to add a third hole, but the way these were designed, I was able to just cut a notch from the middle. Just a heads up, make sure these are the size you need. My baby book is not an office or school sized 3 ring binder. It is smaller like most baby books are.

Nice product. I needed something to secure passports & car titles in my typical 3 ring binder. It's a bit small but still does the job for me. If you need something larger like a paper size look elsewhere.

Using these to organize my circular knitting needles and I love it. I can write on the envelope with a permanent marker and then coil the needles inside. They are sturdy enough to stand up in the drawer I use for knitting needles so this keeps things organized and easy to find.

I am using these to store my steel paper dies for paper crafting (along with magnetic grate covers). Work great! Strong and sturdy. I'd use these again for another project. Nice a stiff plastic.

I love these, and can think of a million things to put in them. You could even cut of the holes for a binder and send it through the mail as an evelope with a fancy homemade card inside.

Love the convenient size.
