We are proud to present our brand-new reusable Neck Warmer. At AQC-shops, we promote natural and reusable items. Our Warmer/ Cold Packs are made out of flannel or cotton, filled with corn. If you want them as a warmer, microwave for about 2 to 3 minutes. Caution: Hot when microwaved, use with care. If you chose them as cold packs, put them in the freezer overnight. This neck warmer is unscented. They are made to order.
