The underside is a lovely soft minky fabric, which is gentle on the skin. This fabric, paired with our beautifully embroidered fabric, is a true classic. Our exquisite embroidered fabric is custom-made for us. It makes this Neck Pillow particularly special. Soothe achy, tired muscles with the calming Lavender scent and moist warmth of our Neck Pillow. The ultimate relaxation treat. Heat in the microwave or tumble dryer; or chill in the freezer! Approximately 14" in diameter and weighing approximately 2.5 lbs, the cover can be removed and thrown into the wash. NS6003
