This GSG Chainmail bracelet is made from Anodized Aluminum rings, 16g. This bracelet is very light weight and easy to care for, and uses an easy close strong magnetic clasp. This bracelet is standard length, and is approximately 7-8" in diameter. If you need a length adjustment, longer or shorter, please send me a message and I will make any necessary adjustments. These bracelets are handmade from opening, weaving, and closing each ring. Each bracelet is approximately 1in wide. Orders will be ready to ship within 48 hours, unless otherwise noted, or if customizations are requested.
