The collars for minimalists made from 100% cuddly, regional organic virgin wool. The retriever collar features a slip-stop buckle that can be adjusted to fit your dog's neck circumference. Gentle on the fur and environmentally friendly, free of harmful substances, and simply naturally beautiful. An occasional wash at up to 60°C in the washing machine regenerates the structure and removes any discomfort your furry friend might have gotten into. Then reshape and let dry. Thanks to the self-cleaning properties of the wool, the collars remain attractive for a long time between washes.
