(2) The physical products remain the property of the provider until full payment has been made.

(2) The purchase contract is concluded once the provider accepts the customer’s order.

Pursuant to Section 356 (5) of the German Civil Code (BGB), the right of withdrawal expires once the customer
expressly agrees that execution of the contract begins before the expiry of the withdrawal period, and
confirms awareness that the right of withdrawal is thereby forfeited.
(1) Customers have a statutory right of withdrawal of 14 days from receipt of the goods for physical products.
(2) The right of withdrawal does not apply to goods
manufactured according to customer specifications or
clearly tailored to the customer’s personal needs
(Section 312g (2) No. 1 BGB).

Payment processing is carried out via Stripe.
