New Hybrid 3-Layer Structure Low to Standard Size 4-7.5cm The item for sale is what's pictured. The original box is not included. Used for about two weeks. It deforms with a squish when pressed, and is soft. I really liked the feel against my head, but it didn't suit me, so I'm unfortunately selling it. The center has a slightly recessed shape, and you can adjust the height to your liking by combining two types of parts with different thicknesses. Please check the product's website for more details. The main black cushion structure tends to attract dust. Also, the dedicated pillowcase has been washed and has small stains and some fraying. Please refrain from purchasing if you are concerned about this. Retail price: 17,800 yen [Model with 8-level height adjustment] Low to standard height [Pillow height is freely adjustable] You can adjust it in 8 stages from 4 to 7.5cm by swapping parts. For those suffering from a stiff neck, and for growing children. [Comfortable sleep] You'll be enveloped the moment you put your head down, like floating on water. [Smooth turning over] The material (TPE) has moderate resilience, allowing for smooth turning over, like rolling.
