These round Cold Be Gone Herbal Wax Melts are perfect for colds and allergies. They are yellow in color and have an invigorating Eucalyptus mint scent and a few mint leaves sprinkled in there. These work great with clearing your sinuses. These are made with soy wax melts. These are hand poured in small batches so the color may be slightly off (darker or lighter yellow color) from order to order. Eucalytpus can be very overpowering, so these are mild. You can't smell it too strongly, but you can definitely feel the effects of it. These are very big. 1.5 oz. each. These come with 4 melts.
