Return Policy: All Sales Final

We take quality seriously. Every product is inspected before it leaves our facility, and we stand behind what we make.

Because we make products designed to go in your mouth, all purchases are final sale. By completing checkout, you acknowledge and agree to this policy. This policy does not affect any statutory rights you may have under applicable consumer protection laws. 

We're unable to accept returns, exchanges, or issue refunds once an order has been placed — this policy exists to protect the safety and hygiene of every customer, including you. Subscription orders follow the same final sale policy; you may cancel future renewals at any time through your customer account portal.

Damaged or Defective Orders

If your order arrives damaged, defective, or incorrect, please contact us within 7 days of delivery at hi@koppen.co with your order number and a photo of the issue. We review each case individually and will offer a replacement or appropriate resolution where applicable.

Chargebacks & Disputes

We encourage you to reach out to us directly before initiating a chargeback or payment dispute — we're genuinely happy to help. Fraudulent chargebacks on valid orders may be disputed with supporting documentation.
