good addition to our construction blocks,
Verified Purchase(What is this?)
This review is from: Sensory Blocks Set (Toy)
I bought this for my 18 months old son and he was fascinated with the blocks. We used them together with the rest of the construction blocks and also just generally shaking and listening to the sound they make.
Also a hit with our 6 years old, who constructs more complicated designs - swimming pools with the liquid blue ones...
