These 60 x 50 mm cotton pads are made in Japan from 100 percent organic cotton without the use of pesticides or chemical fertilizers. The cotton is unbleached and you can still see parts of the stem and fruit of the plant, so it's as pure as it gets! Expect the best juice transfer and cleanest taste of all wicks (even better than rayon). Peel the first and last layer and use the cotton within the pad itself. Must be kept wet at all times. Do not dry burn. Needs to be stored in a cool dry place.
