Each light bangle is approximately 1/10” wide, and each heavy bangle is approximately 1/8" wide. They are made from solid 925 sterling silver. Each bangle has been hammered, then polished to sparkle. They are not connected, so they "clink" on your wrist. The size you choose will be the length of the bangle. Most of my customers choose the length that's closest to the circumference of their wrist. Those who want more movement on the arm tend to add a half inch. NOTE: Each piece is in its natural state. It’s not coated with anything to prevent tarnish. Oils, lotions, moisture, etc. will accelerate the tarnish, so its recommended that you use a jewelry cloth for cleaning after wearing your jewelry. Although extremely rare, some people are allergic to the metals and finishes commonly used in making jewelry. We cannot guarantee that our products are totally free of ingredients that may cause an allergic response in individuals who are sensitive and react to the ingredients in our products. It is the responsibility of the consumer to be aware of any allergies he or she may have to metals (gold, silver, etc.) or the oxidation applied to metals prior to making a purchase. If you have concerns about allergic reactions, you should discuss them with your doctor before wearing our products. Because there is no way for us to know the medical history of our customers, TInk LLC will not be held liable for any allergic reactions that may occur as a result of wearing our jewelry.
