Color: Blue Design: Koala Socks US Size: 5.5-9.5 and 8-12 Sock length: Crew Thickness: Regular Seasons: All season wear Toe : Seamless toe Knitted: A very fine gauge using 200 needles Materials: 79% organic cotton, 20% polyamide and 1% elastane Care Instructions: We recommend hand washing or wash socks in cold water on a gentle/delicate cycle setting. Hang dry and no dry cleaning, ironing or bleaching. After washing they may appear narrower but do not worry, they'll return to the same comfortable length and fit as soon as you put them on. ORGANIC COTTON! Premium quality seamless toe and 200 needle count. Seamless socks are designed to avoid the thick, blister-causing seams along the toes, irritation free for ultimate comfort. 200 needle count means that your sock will be finer, breathable and softer but also stronger due to the density of the stitching.
