It is a thick, single layer watch strap which is great. No glue to come undone, the flesh side of the leather directly in contact with your bare skin. It is veg tanned, so it will mold to your wrist over time.It is quite stiff upon first wear and I foresee it breaking in well, but not getting loose or stretched out. Could be worn casual or formal.I just got this strap, and will update this review as it becomes necessary to. I just wanted to get this review up so that way there's atleast one here for people to read.Buttero leather has a great reputation, and it should be a great choice for a watch strap.
