I don't do much with carved wooden butter and cookie molds which are not my expertise, but as a lover of little carved wooden objects--and modular patterns-- just couldn't resist these, with their perfectly gridded ends. The seller described them as cracker stamps, which I think could just as well mean small biscuits or cookies. Both very much used, with rich patinas.
Dark wood: 3 7/8" x 3/4" x 11/16". Blond wood: 3 7/16x 5/8" x 9/16. Sold as a pair, which is how I found them.
