Castalia 5th Birthday T-Shirt

Celebrate Castalia's fifth birthday with this tee! This short-sleeve shirt is a super soft tri-blend in heathered teal. It features the five platonic solids as ice in rocks glasses. Platonic solids are three-dimensional figures created by combining basic shapes, adding another dimension compared to the original, flat geometry. These forms were formerly thought to be elemental building blocks of the universe. The Golden Ratio, a number that describes beautiful proportions, arises when comparing the solids. 

Also available for purchase at Castalia until we run out.
