Lithos Numeral Stamps

Seventeen stamps of numerals and mathematical signs in the Lithos typeface at 10 mm height, plus one stamp that carries the marks and punctuation, on faces 15 mm across and 30 mm deep. The 6 turns over to make a 9. It matches the 10 mm Lithos alphabet set. There is no border line around the face, so the impression is just the design, and the sides taper so the stamp lifts cleanly out of soft clay. The stamps slot onto the 8 mm wooden rod, which works as a handle, and instructions are included.
