Mendota ProductsPet Leather Snap Leash - Dog Lead - Made in The USA - Chestnut, 3/4 in x 6 ft (Standard)

I would like to order a 6-foot leash, but 4-foot is the only option in the drop-down. How do I choose a 6-foot option?

The Mendota brown leather dog snap leash says it comes in 4 ft. length, but I can't find it to order.
