Navy Biothane & chestnut Italian Valdibrana leather. Hand stitched with Ritza Tiger thread, renowned world wide for it's strength and durability. The leather is a 7.5-8 oz vegetable tanned leather. Heavy low lead solid brass hardware. 
The handy and functional leash has a handle that is attached with a solid brass square so that you can clip the snap to it and wear it over your shoulder if your dog is off leash.
All collars have 5 holes spaced 3/4" apart. If you order an 18" collar, 18" will be your middle hole.
Biothane is a very strong, flexible, waterproof, fade-resistant, stink-proof and easy to clean material that has been used for years to make horse halters, bridles and reins. Although it isn't reflective it is more visible on the road or a trail than leather or nylon and unlike other materials the color doesn't fade.
