Ewe Marking Harness is an invaluable tool at breeding time. This durable harness is made of strong black nylon web. It is water resistant and features nickel-plated hardware. Attached to each harness is a molded nylon plate that holds crayon blocks. The unique angle of the plate allows crayon to fit snugly and hold firmly in position. Plus, all corners are smooth and rounded and will not irritate rams or ewes. Crayons sold separately.
