Unlike the Formula 1 of international car racing, we don't encourage racing through parenthood. Thus we are happy to reward breastfeeding until age 2 with a special order without any special order charges.

The price of the Formula 1-sie is $30.  Shipping is a flat $7 no matter how many you order.  California residents must add sales tax.

About the formulas: Many mathematical formulas are named after Leonhard Euler, an18th-century Swiss mahematician. Our first is known simply as Euler's Formula. By setting x = π and rearranging the terms, the even-more-famous, beautiful Euler's identity is obtained: eiπ + 1 = 0. Our second is called Euler's Polyhedral Formula. And our third is, we hope, known to many non-mathematicians - it's the Quadratic Formula memorized by almost all high school students.
