The bracelet is my “go to” bracelet" & so comfortable & easy. It wraps very easy & hooks on the button stud in back. The Circle - O Ring bracelet is a larger, chunkier style. I have a wrist size of 6 1/2" & this size ring is fine for my wrist size. I do have another style of this bracelet with a smaller ring & thinner width leather. The leather measures 1" wide - this is new leather & has a beautiful oil tanned base for a long life or wear. You pick the ring metal. The rings are Nickel Plated Steel or Natural Brass & measure 2" round (Inside Diameter), 1 1/2" round (Outside Diameter) To determine your size, please measure around your wrist. Use a soft measuring tape right at your wrist bone. If you need custom sizing, please leave your wrist measurement in the note to seller at checkout.
