Will I be fined if I do not return empty cylinders on time? Webshop

If multiple orders have been placed but no returns have yet been received by us, we will contact you. Several reminders are always sent by email from our system. If, after no hearing or telephone contact, we still have not received a return within the agreed term, we will charge the costs of a set of empty cylinders. The costs for not returning empty cylinders are € 40.
