We are having a lot of trouble ⚠︎⚠︎⚠︎ Thank you for looking at our items from among so many. Please take a moment to read our profile. For packaging, we use recycled materials such as used wrapping paper, plastic bags, and flyers. We will compress items for shipping, so they may arrive wrinkled. We live with cats, so cat hair may often be attached to the items. Even though we are careful, we have multiple cats, so it is unavoidable. If you have allergies or are sensitive to cat hair, please refrain from purchasing to avoid trouble. We ship within one week, so please refrain from purchasing if you are in a hurry. We will ship via the cheapest method, either standard mail or Mercari delivery. Please understand that standard mail does not have compensation or tracking in case of loss. *We take photos of the packaging before shipping. Please understand that we are not responsible for any damage, loss, or other issues after shipping. We do not accept returns due to malfunction claims to prevent fraud.
