The all natural flaxseed filler provides a gentle, moist heat that can be reheated again in the microwave or even cooled in the freezer. Use for anything from body aches to headaches, or simply to add a little extra warmth under the covers. Each is completely one of a kind in appearance as they are crafted from botanically dyed cotton canvas cut-offs. For that reason, the one pictured may not be the one that is received upon ordering. Roughly 6”x 10” in size.
