I agree with AerynKelly. The sleeves are floppy. Maybe I could get some cardstock to put in it to make them stand up. I don't know why I thought they would be clip up. I use several brands of stamps, too, and more than half of them did not fit. And here is the million dollar question--where do you get extra sleeves? I don't see any on this site. Now my search is on. I'll try to make the most of it.
(two days later)--I sized cardstock and put in the sleeves and it makes it ever so much better. I did find extra sleeves on a different site, also. So, I will use it for my small sets.
