Pi Day Wrap Tumbler Geek Gift


Have your pi and drink it too!

Our copyrighted spiraling Pi cup design will delight your math teacher, engineer, or inner geek. Featuring Pi to 10,000 decimal points, your favorite non-repeating number is contrasted against the pi symbol on a durable powder-coated, full wrap, laser engraved stainless steel tumbler. Keep your drinks icy cold for 24 hrs or coffee piping hot for 8 hrs  while you do nuclear physics, rocket science, or just monotonously grade papers.

Turnaround time is about a week for in stock colors. Backorders are filled in the order received as inventory becomes available.

Order by March 1 to guarantee arrival before your Pi Day, 2018 party.

Upgrade your drinkware!
