Great selection the children loved them. The fossil collection was too small to use with them but still a great collection.

I bought these rocks for my neighbors child who has a fascination with geology. I only wish that the teaching sheet that came with each set was larger print.

This set is great. The kids love being able to see and touch all the different types of rocks that we are talking about during our geosphere unit in Science.

Big rocks and there is a great variety within the complete set. The price was comparable to other companies until it was increased by $20 in 2012. Could be packed better, but overall I was very pleased with this set. Comes with a guide in each box.
