70 Glow in the dark and 30 natural blocks come in this new set of blocks. If you expose them to light for 10 minutes they will glow for over 40 minutes. These are fun to use separately or as additions to other building sets. We can report that they do work and add a new kind of sensory dimension to building fun. Build before bedtime and there is a nightlight when the overhead light is turned off. Also new this season, a set of Neon color Citiblocs.
