In order to return an item you need to first obtain an RMA (Return Merchandise Authorization) number. To request an RMA number, call 781-491-0141. Place item in its original packaging into a shipping carton. Include the invoice and the reason for the return. If defective, please specify the defect. The RMA number must be clearly written on the shipping carton. If you received a label in the email, stick the label and tape it to the carton. We recommend that you insure the package and ship via a traceable method. Return shipping charges are the responsibility of the customer.
