Unique interlocking blocks for children 3 & older that help foster problem solving skills and constructive building techniques. Children instinctively respond to the soft material which also makes playing ouch-free; no need to worry about stepping or sitting on SOFT BLOCKS as they will just softly bend and squish. Unlike small hard plastic building blocks which little fingers can have a hard time snapping together and prying apart , Soft Blocks fit together and come apart with ease. SOFT BLOCKS float, and are great for the pool or bath, too.
