Hand-knitted sock covers. Due to their thickness (volume), bulk purchases of sock covers are not available. The yarn is knitted with 5 strands: 1 strand of alpaca-blend mohair, 2 strands of 100% wool, and 2 strands of polyester and rayon. They are warm. Size: Length: Approximately 24cm, Width: Approximately 11cm Length from heel: Approximately 13cm. The yarn stretches, so they are suitable for those with feet 24cm to 25.5cm long. The wool is red, random black, and gray-green. The mohair is wine-colored. Please refer to the photos for the other colors. They are made with care, but there may be some imperfections. Please refrain from purchasing if you are overly concerned about minor details. Thank you.
