Genuine Possum Fur Willy Warmer…. or Peter Heater as the Australians call them. And, before you ask – no this product is not available in Extra Extra Large size – buy a possum scarf if you are really worried. Great novelty, one of our most popular lines. Great as a gift for your male friends back home (no we don’t do Extra Small sizes either sorry). All possum fur is treated and is fine for export.
