This is a Guin Neck neck pillow. I purchased it new and have used it a few times. I have disposed of the box and instructions. It appears white in the photos, but it is black. I don't think there are any noticeable stains, but please understand that this is a used item. I will ship it in a cardboard box I have at home. As of October 2025, a new one was 6,540 yen at the official Rakuten shop. 【Product Description】 Brand: MAOMA Features: Neck pillow Color: Black Size: Approximately 22cm wide x 20cm long x 9cm high Target age: Adults Product care instructions: Machine washable Feel refreshed in just 1 minute during your free time!
