Great, affordable product all around.
To the previous poster. I think you are to stamp the image on one side to create an "index", and place stamp on back. When you file the boards away, you can flip through and see the images on the index side. I know it is more economical to use both sides for storage, but don't think that's the intent.
I love the concept of this product and will use it but I do have a couple of frustrations. The user is instructed to stamp an image onto the card with STAZon ink, which I did, but then the image is backward when the stamp is turned over so that it will stick on the plastic card. Also, by the time the stamp is removed and reapplied a couple of times, even the STAZon ink is coming off. The other frustration is that the acrylic stamps stick to the plastic card in front of it and get pulled off. I had to cover the stamps with their original protective paper to keep this from happening. Suggestion: Include, with the cards, the same clear material that come with acrylic stamps. Make them the same size as the card. Then, the the stamp can be used to stamp the figure onto one side and, when the clear sheet is turned over, the actual stamp can be placed onto the card just below the positon of the stamped image. This will allow the stamped image to be in the correct positon and not be rubbed off by the stamp.
