"Blueberry Pi" Math Dots Short Sleeve Pocket Tee

Size Guide

This product has been discontinued.

Math is everywhere - but most especially scattered across this polka dot design! Circles in shades of blue pop with equations, graphs, and calculations, and prominently featuring pi, our favorite irrational number. With navy sleeves and matching breast pocket, this will be his (and his math teacher’s) absolute favorite shirt (except on test days).

Made ethically in Hong Kong.
