Another Yelper brought me here recently and I was blown away the quantity of rubber stamps. The organization of the stamps needs explaining so your best of telling the sale clerk what you're seeking. If you're just browsing, you can be here a very long time. I came in with no need for any rubber stamps but ended up buying 4 of them. Now I'll probably go back there to buy ink.
I highly recommend this shop since it's so unique and it's fun to find something so focused on one hobby.
