This is a Miffy silk nightcap from a studio CLIP collaboration. I used it once after opening it, and then didn't use it again, so I'm selling it after storing it at home. The following is a copy-paste of the product description: Collaboration original patterned nightcap. The original pattern makes it a rare item that you won't find anywhere else. By using a silk blend material that is gentle on the skin and hair, it prevents dryness during sleep, and wearing the cap also reduces friction between the hair and the pillow. * Due to the nature of the product, there may be individual differences in texture and shape. * Due to the nature of the fabric, there may be slight thread pulls due to the sewing, but please understand this as a product characteristic. * Slight wrinkles may occur in the rubberized areas, but please understand this as a product characteristic. * There are white spots on the product backing card, but please understand this as a product characteristic.
