Each vintage black plastic Tri-Omino includes 3 indented white numbers - 1 in each corner. The sides of each Tri-Omino measure 1-1/2 inch; and from the point to the opposite side is about 1-11/16 inch.
Each set is a lucky dip: randomly packaged in groups of 3 Tri-Ominos.
Some photos include 4 for illustration only.
