Palomine Lines are made with BioThane®, an excellent leather alternative. They require little or no maintenance. When they get dirty, they can be wiped down with a damp cloth or washed in a bucket of soapy water. Double riveted with solid brass rivets for extra security, they are made to withstand all environments, terrain and weather. Palomine Lines are made in the USA with components made in the USA, when available. Made-to-order according to customer specification, Palomine Lines are the lines every dog owner/handler wants among their dog training equipment.
