These cubes are really great, easily learn the differing weights of the elements however the cubes are very, very small. Will not work for students in a classroom as they will easily be lost. Think 1/8 inch square, a bit bigger, but for a high school student or adult they are really cool.

this carbon cube is the coolest item to have, it lets you feel the material and the weight.

I don't have the scales and beakers to test the claims for 99.999% pure. I sure like the comparison cubes. Sometimes it is hard to comprehend the density and weight differences of elements until you have a set like this. Highly recommend.

They’re smaller than I thought but really makes you think of molecules and molecular structures. They’re a definite conversation piece.

These cubes are really cool all 15 of them order came fast also order was packed perfectly and with care. I messed up on ordering this I apparently ordered the tiny ones not the 1 inch I only put this in the review so others won't make the same mistake it's not the shippers fault I was going to took off a star because a few cubs had scratches over the information area but was still so happy with it I ordered the gallium metal I can clearly still see info no big deal.

1 inch cube, arrived safely and intact with only minor loss of sharpness in some corners due to being filed that way or transport trauma. Amazingly heavy. Very beautiful.
