This was a perfect gift for the math nut.
A unique Christmas gift.
Delighted to find this company!
Worried about the formulas coming off in the dishwasher. Nothing worse than a half-formula! Will just be careful.
It was the ideal gift for someone who has everything he want and needs.
Fun & whimsical.
It was a gift for my daughter! It is as though the glasses were custom-made just for her!
The glasses are smaller than I imagined. Probably should have read the description better. We'll see how they hold up to washing. Love the detailed artwork and the graph denoting the constant's value compared to 4 ounces.

It was a gift.
My son will use them to entertain his guests.
