The base comes with 10 pockets that can fit 2 stamp sets in it. There are also extra packs of clear pockets you can get separately, which you will most likely need. The stamp holder retails for 39.95 and I will have a few coming in on Tuesday or Wednesday this coming week.
My only complaint with this item would be that the pockets should be bigger. Most of my stamps will fit inside the pockets, but some wont. For example, Penny Black stamps are too big to fit. If you want me to hold one for you just send me an email and I will set one a side.
