These are 2 pair of Pacas, Ladies size M-L. Company says: "Warm and durable, while still breathable and light. Buttery soft socks made with Alpaca. They are soft as cashmere, non-itchy & hypoallergenic, eco=-friendly & sustainable and thermoregulating." These are the most comfortable socks, but I now am only wearing solid colors. Both pair are made with 38% Alpaca and 30 % Acrylic. The beige (6027) are also made with 23% Nylon, 6% Olefin and 3% Spandex. The black pair (3305) also include 28% Nylon, 3% Spandex and 1% Olefin. They are machine wash cold. They are new with tags. From a pet and smoke free home.
