This low pillow is still backordered as of December 2025 and often sells out. I liked it when I used it at Super Hotel, and after purchasing it online from the official store, I only used it for 2-3 days. It's not new, but it's not worn out, so I think you can use it with confidence. The following is a quote: Key points of the "Mochi-Fuwa Ladies Pillow" * Three-dimensional structure with unevenness, considering the curvature of the cervical spine when sleeping on your back, the fit of the round head, and the shoulder width when sleeping on your side. * Adopts a gentle round design to fit snugly against the shoulders, making it easy to turn over. * Uses far-infrared ray emitting threads. Far-infrared fibers radiate far-infrared rays contained in your body temperature, working on the body's original power to regulate the internal rhythm, providing comfortable sleep and relaxation effects. * Uses Biorex fiber as the material inside the pillow. Biorex fiber is cotton made by culturing corn. Since the raw material is corn, it also has the characteristic of biodegradability, making it an environmentally friendly material.
