This U-shaped neck pillow, sold at airports, is made of breathable mesh material for comfortable support. I seem to remember it costing over 5000 yen at the airport. - Brand: gowell - Color: Blue Gray - Material: Mesh, Polyester - Design: U-shaped - Adjustment: With strap The cover is removable and washable. I used it only once, and it has been washed. As you can see in the third photo, there is a small white stain, but I think it was there originally. Thank you for looking. Instant purchase is OK.
