What should I do if my parcel or product arrives damaged?

If your parcel arrives damaged or the product shows visible mechanical damage (e.g. cracks, scratches, dents), please check the parcel in the courier’s presence and fill out a damage report.
This document is required to submit a claim to the courier company.

If the damage is discovered after delivery, you still have 7 days from the delivery date to report it, preferably directly to the courier company. Please include photos of the damaged product and packaging.

Without a damage report, the courier company may reject the claim, so it’s always best to check the parcel before signing for it.
If you’re unsure how to proceed, please contact our customer service team – we’ll guide you through the complaint process.
