Stamp of Approval is the only store specifically geared toward rubber stampers in Boston. It is very small, and has a rather limited selection, but is still worth a visit! While they do have a limited space, they sure pack as much in as they can!! You will find a good selection of basic products, and some great kits and magazines as well.
The staff is occasionally friendly, but often just pretty much ignore you. Since it is the only store to buy some of the products that they offer in the area, I will put up with that. I miss the friendliness of some of my favorite stores up in Maine however. The staff doesn’t always seem as knowledgeable as they could be, and half the time I visit, they are on the phone the whole time.
However, if you find yourself in Boston and craving a new rubber stamp or some inkpads this is a convenient place to visit. It is in Fanueil Hall, and is close to several different T stops.
