I create this bracelet from copper. I use copper tubing and air hammer it. This creates air pockets so it looks puffed. I like to call these my " Moon Craters". Copper is known to help arthritis so I keep my bracelets natural however with age they will naturally patina to a burnished brown color. If you want to keep it shiny I can shellac it with a clear coat but this diminishes it's value for arthritis help. You can also keep it polished with a polishing cloth or metal cleaner. If you would like me to shellac this cuff choose that option in product options. Otherwise I will leave it in it's natural state. This bracelet/cuff has an inside diameter of 7" and is 1" wide this is a heavy duty bracelet. I will make it to your size just leave a note when you checkout. See sizing tips below. MAKE SURE IT FITS, TIPS ON GETTING THE SIZE RIGHT BRACELETS---Using a flexible measuring tape, measure just above the wrist bone, then add 1/4" to 1 " (1/2" is average) depending on how tight you like your bracelets to fit. This is your bracelet size. ANKLETS--Using a flexible measuring tape (or string) measure just below the ankle bone. Tighten the tape or string so it fits snugly, but not too tight around your ankle. Add about 1/2" to the measurement. This is you anklet size.
