Mitten tops, palms, and cuffs are 100% rich, soft alpaca from Peru. The black back is 100% wool. Colors are black, red, blue and teal. One size fits all; however these will fit best size Medium or Large. Total length including cuff = 10". Personally handcrafted by me in my pet-free, smoke-free home. Completely lined with soft anti-pill fleece to make them super warm. Mittens are washable; lay flat to dry. Alpaca sweater labels are included in last photo. I have lots of mittens posted - check them out!
