Refund processing

Approved refunds are issued to the original payment method used at checkout. Depending on your bank or card provider, the funds may take 5 to 10 business days to appear in your account.

If you paid with a local European payment method, the refund is routed through the same provider. We cannot refund to a different card or account for security reasons.

Replacements are sent only after the original item is received and inspected by our quality team. We cover return shipping for approved claims; unauthorised returns are sent at the buyer's expense.
