Product title: Sachi Organics Buckwheat Hull Neck Pillow Small
Product description: Buckwheat hull sleeping pillow. Our pillow is professionally made in America with the finest domestically grown organic raw materials. The 14x20 size is great for a sleeping pillow size. This size allows for the proper support needed for a healthy nights sleep. Buckwheat hulls are hypoallergenic. They regulate temperature and allow for air circulation. Conventional sleeping pillows are filled with unsupportive materials that contribute to muscle tension and lost sleep. This pillow is perfect for back, side and stomach sleepers. We fill it full so you can customize the support level to exactly what you need. There is a zipper opening for easily adjusting and cleaning the pillow. To clean simply pour hulls in a bag and wash the case in cold and dry on normal. Inside: Organic Buckwheat Hulls. Outside: Cotton Canvas made from organic fibers. Our family has been professionally manufacturing buckwheat hull pillows for over 30 years. Buckwheat is considered to be firm by most people. Buckwheat is sometimes considered to be noisy for light sleepers. This pillow can also be filled with millet hulls upon request, which are less noisy. Just message us when you purchase. Buckwheat Pillows are very unique so be sure this pillow is right for you before making your purchase.
