Refill, Save, Repeat! 

The Otter Student Union and the Sustainability Office are excited to bring Wonderfil to your OSU Lobby—a refill station that makes it easy for CSUMB students and staff to cut down on plastic waste while saving money.

Wonderfil is a women-owned, Santa Cruz-based company leading the way in refill technology. Their mission is simple: help people swap out single-use plastics for sustainable solutions—right here on campus.

What can you refill?

  • Shampoo
  • Laundry Detergent
  • Dr. Bronner’s All-Purpose Soap
  • Moisturizing Hand/Body Wash

(All products come from sustainable, high-quality manufacturers—many based right here in California.)

Why Wonderfil?

  • Students spend an average of $36/month on products like these. Refilling saves money and reduces waste.
  • Every refill = one less single-use plastic bottle in the landfill.
  • It’s quick, easy, and located right in your OSU Lobby.

Come refill, renew, and be part of a greener, more sustainable CSUMB!
