Review: Multi purpose, excellent purchase, highly recommend! - This product has several uses and should be a favorite of your child for several years. Other manipulative toys have been a big hit so I purchased two sets of these for my grandson. They are smaller and will develop more fine tuned skills as he masters fitting together and building. There are 8 colors, 25 of each. He is using them for counting, sorting, matching, making different sets. So much to do that he has not become frustrated or lost interest while attempting to fit together. He says that he will try again later and continues to play with them. They are nicely packaged in a snap container with handle. One word of warning-I purchased two sets, as they were well made and reasonably priced. His 34 year old mother kept a set for her use! They are pretty and work her fingers for piano. I am ordering more as gifts, and one for me! I have MS and these are a great physical/occupational therapy tool for my hands.
Review: Great toy - Awesome toy! Fosters lots of creative play! We used them for Easter egg fillers instead of candy! The kids loved them!
