Great variety
"These blocks seem to be of excellent quality, smooth finish, no rough patches. I'm curious how the water blocks will age but they look great and don't seem to have any risk of a leaking or drying out currently. My toddler loves the variety of noises/visual effects when shaken. I think they're a great set for young toddlers to explore as sensory objects and would be fun as an addition to a block set. This is a cost effective way to try each of these special types of blocks. I may get larger acrylic rainbow blocks to use in the future, but for now this is great."
