This is our first in the let's investigate style but we are huge Yellow Door fans! I can't wait to get more of these. I love how they are double sided so you see the dinosaur and the footprint. So far we have used these with kinetic sand and dough parlour and they make perfect prints. I can't wait to take these outside. We also have the dino bone set so I like that I can do sensory bins with both now.

We own the entire line of lets investigate! they are wonderful for indoors and outdoors, mud, sand, water and kinetic sand inside! Also play doh! so many uses! def recommend this series to everyone! they are also very large! Great to pair with sensory tables! This dino set also pair wells with the dino bone set by yellow door!
