If you would like to return any item(s), please contact us by either emailing info@dittools.eu or calling (+372) 5556 0057. We will share with you a Return Merchandise Authorization (RMA) code and ask that you clearly mark this code outside of your shipping box as you ship your item(s) back for a refund.

Do not forget to cover or peel off any existing shipping labels on the box.

Customs, duties & taxes
There are no customs duties or taxes on orders shipping within the EU. Orders shipped outside of the EU may be subject to import taxes, customs duties and fees collected by the destination country. The recipient of an international shipment may be subject to such import taxes, customs duties and fees, which are collected once a shipment reaches the recipient's country. Additional charges for customs clearance must be paid for by the recipient; we have no control over these charges and cannot predict what they may be. Customs policies vary widely from country to country; and when customs clearance procedures are required, it can cause delays beyond our original delivery estimates. We advise that you contact your local customs office for more information.
