Wickett and Craig Ungazed Harness in Olive is a beautiful full grain vegetable tanned leather. Wickett and Craig is a US based tannery that was founded in 1867 and is well known for their quality.
The unglazed characteristics leaves the leather open for patina and color changes over time as you use and carry the wallet. Over time the deep Olive coloration will darken and take on a life of it's own. The olive particularly has a lot of depth to the color that shows really well in person.
