The Lenwood leather collar is handcrafted out of the same premium leather that we build our belts and harnesses out of. Collars are 1″ wide and are custom built, one at a time after your order is received. Options are stainless steel or black hardware on our K9 gear for long life and reliability. The collars feature 7 adjustment holes that are 1″ center to center (3/4″ edge to edge). The length you order will be the middle of the 7 adjustment holes so you will have 3″ of adjustment each way.
