This Triskelion Celtic Necklace is 50 cm long and crafted from stainless steel - an incredibly resilient material that won't rust or cause an allergic reaction, while remaining resistant to acids and alkali, with no risk of deformation or fading! 🤩 For maximum longevity, keep it away from water, sweat, and cosmetics and be sure not to wear it in the shower, while swimming, sleeping, or exercising. Store in a sealed bag or box and use a soft cloth to clean it with extra care - no yanking or throwing it around!
