About Serpentijn

Our Purpose

Serpentijn was founded to make a positive impact through art and athletics, based on the belief that both play a vital role in learning and living life to its fullest. This idea grew into collaborating with artists to create beautiful, functional products in order to support our non-profits of choice.

We anticipate our product offering expanding over time, and are excited about partnering with new artists and non-profits. Our goal is to serve these communities through a shared love of art and athletics.

How It Works

10% of each purchase you make goes to a worthy non-profit organization, selected by you during checkout. For 2023, your choice of charities includes:
