I am selling these because they don't match the atmosphere of my home. I installed them in a room once, so they have been opened, but I removed them immediately. They originally have a smell like fabric glue, so please wash them if you are concerned after they arrive. Please feel free to comment if you have any questions♪ ※Regarding shipping during the New Year's holiday Please note that shipping is not available from December 30th to January 5th.
