Description The Jimi martingale is adjustable and can be opened and closed. The martingale provides a gentle way of preventing your dog from pulling out of its collar. The Jimi collar is constructed with both a pin-buckle and martingale front – it is therefore adjustable, and a good choice if you are looking for a safety collar that is easy to slip on and off. Designed with a classic slimline cut and fitted with solid cast brass hardware. Made by hand in agile vegetable-tanned leather and pure new wool. Wool is a great choice for sensitive skin, it is naturally self-cleaning and has a great ability to prevent bad odours, it also provides comfortable, soft support.
