Buckwheat hull pillow
Reduces stiff neck. If not,
A true marketer!
I couldn’t stand stiff neck anymore and decided to change my pillow into buckwheat hull. Once I tried one prominent brand but it felt too high (don’t like thick pillow) and it ended up stored on the rack.
Sobakawa pillow seems to be a very promising cure. Let’s wait if it really works, or the marketing just works.
