This is a Hotto Suru Pillow Plus (genuine product). I used it a few times with a pillow cover on it, but the height didn't suit me, so I'm selling it. It has a warming and vibration function. The white pads are for height adjustment. Everything that can be washed has been home-cleaned. You can use it right away. There is no box or instruction manual. It will be shipped using recycled packing materials. Please refrain from price negotiations. - Color: Gray - Type: Support Pillow - Remote Control Function: Neck and shoulder vibration function - Features: Design to support neck and shoulder muscles
