If you no longer have the shipping bag or box that was used when the package was shipped to you, you can use another bag or box to ship it back to the shop. *
You should however always make sure that the package is properly sealed, so the item is not damaged on the way back. 🙏
*Original packaging for items like shoe boxes, jewelry boxes etc. should always be returned with the item but should never be used as the shipping box, as this might decrease the value of the item.
