I like the holder. I don't like the sleeves. They are too wide for most of the stamps that you buy now a days. I had to fold them over and tape them to hold the stamps that I have. Also, it doesn't hold very many stamps.
That downside to this is that the sleeves are NOT wide enough to store the sheets that the stamps are stuck too. I had to rearrange the stamps on their sheets then trim the sheets down.
