Gently used Glerups - unisex, size 40 (US 9 women’s) - patina started on the soles. From Glerups website: Our slippers are made of 100% pure, natural wool in the classic colour petrol with a sole of soft and chrome-free calfskin. We started making slippers over 30 years ago - in fact, our founder Nanny Glerup made the first pair of slippers as a declaration of love to her husband Ove. All slippers are produced in our own factory and in our special glerups wool mix, which makes the slippers itch-free and durable. All slippers are designed and produced with respect for animal, people and nature.
