This is a great looking casual copper cuff. It is what I consider a medium sized cuff. The opening measures 1" while the inside is 2" by 2 1/4".
A number of hammering and polishing techniques have been used in making this cuff. I have oxidized it a bit and also polished it with wax to try to keep this color as long as possible.
You do know though that copper has a life of it's own and will change color with age.
