From LM Products:

Quite possibly the nicest leather we’ve sourced in years. It has rich undertones that spring to the surface, adding a rich and subtle bust of color. The luxe leather has a smooth surface that will age beautifully with time and travels. It also features a soft & supple premium leatherbacking layer- giving it the perfect combination of looks, strength, and comfort.Color: BrownWidth: 2.3″ or 2.9″Length – 37″ – 58″

Notes on width – 2.3″ is just slightly narrower than a 2 1/2″ strap & 2.9″ is just slightly narrower than 3″. 2 perfect sizes!
