Microplastic Status

We could not fully establish everything Frank Green Ceramic Reusable Cup 355ml is made of, or its materials (stainless steel body, ceramic interior coating, Tritan push-button lid) sit in a class where the published evidence is genuinely mixed. "Likely Free" is not a signal that the product does shed microplastics — it means we could not get far enough to say that it does not.

How we assess products

About This Product

The Frank Green Ceramic cup uses a stainless steel body with a ceramic interior coating — the drinking surface is ceramic, not plastic. However, the push-button lid mechanism uses Tritan copolyester. Classified as likely free because the primary liquid-contact surface is ceramic, though the lid is plastic.

Materials

  • stainless steel body
  • ceramic interior coating
  • Tritan push-button lid
