Here is a 10 piece Stacker set of Elephants. Made with MDF material for strength. 8 of the 10 Elephants have letters cut out in them. The ultimate challenge is to stack all the elephants and spell the word “Elephant” from top to bottom. It’s quite a challenge. This stack, like all of my Stackers will stack a million ways. Instructions included and it comes with a nice plastic box for safe keeping.The largest piece is 5 X 6 in. in size and the smallest is 1 X 2 in.
