For those who don’t round. Not at restaurants. Not on taxes. Not in life.

This shirt is for the uncompromisingly precise — the engineers who measure twice, the mathematicians who side-eye 3.14, and the detail-oriented minds who believe “close enough” is a personal insult.

Featuring:

π = 3.141593. THE PRECISION

Because stopping at 3.14 just feels… irresponsible. Clean, minimalist, and quietly clever, this tee delivers math humor with restraint — the way it should be. A Perfect conversation starter for people who notice decimals.

It’s ideal for Pi Day , lectures, lab days, or casual Fridays where accuracy still matters.
