Permanent jewelry is not as scary as it sounds. Nothing goes into your skin, and it doesn't pose any safety risks. It's a length of chain (bracelet, anklet, or necklace) without a clasp. We connect the ends with a jump ring, and weld it closed so that it stays on. It's not indestructible, and should still be cared for like all jewelry. We love to layer ours up - one just isn't always enough!
