Brand: CHARM Material: 100% Silk Made in Japan Washing Instructions: Please handwash your beanie using a mild, soapy detergent meant for delicates that does not contain bleach in lukewarm water. Wash gently in the water for 2-3 minutes; then let the garment soak for 3-5 minutes. Do not wring or twist your silk garment while it is in the water as silk gets weaker when wet, and the beanie may lose shape. And do not soak the beanie in water for long periods of time, since this may cause the eventual fading of the color. Once you're done soaking, rinse out the soap in running cold water. To dry, roll the beanie up in a towel and squeeze gently until most of the water has been squeezed out of the beanie. Silk dries quickly so after this place the beanie on a flat surface to dry away from direct sunlight.
