You can put together our NOOFF collars and leashes yourself. All collars and leashes are handmade by ourselves in our own workshop. You can add your dog's name and/or telephone number, so you have a unique collar or leash for your dog that hardly anyone has! All our NOOFF® products are made of vegan leather Biothane and are therefore easy to clean, do not smell and are waterproof. Do you have questions about one of our NOOFF products? Send us a message!
