I've got 3 different sets of puzzle exercise mats available to sell. There are two small sets (one all black, one multi-colored), and one large set.
The large set mats are about 24"x24" per square, and there are 12 of them. I'd like $4 for each, or $40 for all of them (a set of these same ones are selling on Amazon for $70 right now).
Both the small sets are 12"x12" per square, and are going for $2 each. There are 14 squares in the multi-colored set, and 20 squares in the all-black set. However, they are different thicknesses, so the sets would not work interchangeably.
All three sets were used very minimally and are still all in excellent condition. They also come from a smoke-free home.
