Pi (8 Pack)

The pi symbol in confident brushed strokes, mathematics' most famous constant worn as a badge. It is the tattoo equivalent of a favorite theorem: irrational, infinite, and quietly proud of it.

Size & Placement

The pack includes eight 2.4 x 2.4 inch tattoos, at home on the wrist, forearm, or behind the ear. It is the obvious gift for math teachers, engineers, and anyone who celebrates March 14th.

Semi-Permanent Ink, No Needles

The ink is semi-permanent: it develops over 24 hours and lasts up to 10 days, a finite run for an infinite number. Needle-free.
