How will you paint yours?!
This mould is made from thick ABS plastic. You'll get some pretty impressive casts out of this one!
If you'll just be casting the Lizard part from this mold then they'll measure just under 12½" x 6½" (31cm x 17cm) and they'll be just over 1" (26mm) deep.
However, you could also cast the rectangular base part to this mould as well. This would make the overall dimensions approximately 13¼" x 7½" (34cm x 19cm) and approx. 2" (5cm) deep.
