Density Blocks Set Of 18 Review

Based on my experience, I was disappointed with this product. Despite the product being marketed for science education, the density blocks lacked accuracy and CONSISTENCY in measurement. The blocks are made of cheap materials, giving off a low-quality industrial and scientific impression. .

This item was a gift to one of our grandchildren who is very interested in rocks and minerals. He was very pleased with such an interesting demonstration of these elements and discussed with us how he would use them.
