Here's the number set to go with the Fortress alphabet! It includes the "No." stamp to go with them, cool! Available in LARGE, to match the alphabet, and in a smaller set, too, 3/4" tall. I don't know about you, but I totally LOVE numbers. (Oh, and please note that in these sets, the 6 and 9 are one stamp!)
LARGE SET, #AL-1016 $12.00
SMALL SET, #AL-1018 $5.00
Scroll down past the set to see the BIG numbers, in just about the size they actually are!
