This is a nice set by Pottery Barn Kids "Let's Learn". These are wooden creativity cards to use your imagination with while building, stacking, constructing, creating! They are painted in bright colors and the wood is thick and durable. The Set comes with 10 Large Slotted Cards & 10 Small Slotted Cards. This educational toy-encourages creativity and the use of imagination for designing whatever you come up with! The 10 larger wood stat blocks/cards are approx 10 x 6 1/2 and the 10 small are approx 6 x 4 in. My grandkids loved these and just created new objects each time they played. Please no crazy offers, due to the fact that I will have to create a larger shipping label and I will be literally giving them to someone at that which is fine just so that someone can have a good time with this toy.
