Perfect for home chemistry
This was perfect for an entry to endothermic vs exothermic reactions for my kids, as well as the differences in properties of different metals.

The picture is misleading
The reason I gave only 3 star because the picture is misleading. What you get is only one container not two.

Arrived as expected
Arrived with a thin oxide layer coating it, but it happens with mineral oil. Cleaned it up and it looked brand new. Helpful and friendly customer service as well. :)
