【Product Description】 This neck pillow offers elasticity and 360-degree neck support. It features a three-dimensional design that prevents stress on the neck by keeping it straight, with a height of 12cm on both sides, which helps prevent the neck from bending or straining during sleep. Made with a material that won't deform even after long-term use. The cotton core weighs a light 220g. When storing, simply roll it up and put it in the bag for compact portability.
