Return and exchange are only available through the showroom. The courier company does not allow customers to check the products and they do not collect orders from clients. So please check the color and size of product mentioned in the description before you make the purchase.
You can always contact us for any return question at info@mimilinens.co.
Exchanges The fastest way to ensure you get what you want is to return the item you have, and once the return is accepted, make a separate purchase for the new item.
