Considered “the next little thing,” these little blocks ($19.95-$24.95) are the same great COOLBLOX in a mini size and price. These delightful little foam blocks are smooth to the touch, colorful, safe, easy for little hands to grasp and fun to use. This unique foam building set with interlocking design got high marks from testers because it is so lightweight and harmless even if it is thrown. Also, it makes a great travel toy as it comes with its own plastic travel bag.
