Thank you for viewing. This is a germanium low-resilience pillow with mesh material for excellent breathability. The box is included, but there are no instructions, so please check the images. I bought it, but the height didn't suit my neck, so I'm selling it at a low price. Size: 33 x 46 x 10cm - Color: White/Black - Type: Neck pillow - Material: Mesh fabric - Design: Three-dimensional shape
