This rice filled pillow is sewn into channels to keep the rice from sliding all to one side. When heated the pillow will give you relief from aching muscles and a nice aromatherapy from Lavender flowers.

Seams and filling may change size by 1/4 inch. Please select style. Ships only in the continental U.S.
