Celtic Knot Copper Cuff Rustic, recycled, therapeutic, and natural! Appealing to men and women alike, this unisex copper cuff bracelet is individually handcrafted using reclaimed copper. Each cuff is provided with a naturally rustic patina to highlight the design and emphasize the organic characteristic of copper. The front of the cuff is enhanced with a version of a Celtic Shield Knot. The Celtic Shield is a looping knot with four corners, typically symbolic of unity, inner strength, and protection (both physically and spiritually). The durable 1-inch-wide cuff is forged by hand in Colorado and designed to be worn anytime (even in the shower). Therapeutic Aspect : Some believe copper to have a therapeutic benefit. For centuries, many cultures have realized the beneficial effects. In contemporary times, it is thought that copper micro-nutrients absorbed through the skin help relieve symptoms of arthritis, rheumatism, tendonitis and muscle pain. While the exterior of the bracelet has a polished finish, the interior is unpolished, allowing bare copper to touch the skin. Worn against the skin, all copper can potentially leave a slight green tint - this is not an allergic reaction, rather a desired natural reaction to pure copper as the micro-nutrients are absorbed. Most all skin types will experience this. Recycled Materials : The cuff is crafted with reclaimed copper using sustainable and responsible methods. Although crafted of pure copper metal, the "pure" copper may contain trace elements of zinc and/or tin, which are also considered beneficial nutrients. However, the copper is completely nickel-free. Sizes : The Celtic Shield Copper Cuff is available in small, medium and large sizes to fit all wrists. Small is suitable for wrist sizes 6" to 6.75", Medium suitable for 7" to 7.75" and Large suitable for 7.75" to 8.5" (most men will wear medium or large sizes). Each can be initially adjusted slightly to provide the perfect fit. Fitting Tip : To prevent metal fatigue, do not bend and re-adjust the bracelet every time is is put on. To take the cuff on and off, relax the wrist. At 1/4 to 1/3 of the way between the wrist and elbow, slide the cuff on (as there is less bone mass here). The cuff can then be slid down to fit between the wrist and hand. Initially, adjust the bracelet once so that there is an opening of 1" to 1.5", allowing the cuff to be put on and removed at the same location each time. ~ Made by hand in the USA ~ bracelet width: 1.0" materials: solid copper
