Some colors just get it right. This is one of them. Solid cobalt glass that looks almost black in low light, shifting to a deep, pure blue under the sun. This glass plug has a satisfying weight and a smooth, non-porous surface that's ideal for healed stretched ears. The single flare design means no fighting to get them in - just a clean, simple fit secured with a black o-ring. This is the kind of staple body jewelry that doesn't need to shout. It's built for people who are past the early days of ear stretching and know what good glass feels like in their gauges. Material: Solid Soda-Lime Glass Available Sizes: 4mm (6g) - 16mm (5/8") Type: Single flare glass plug w/ o-ring Sold As: A Pair Wearability: Best for fully healed lobes. The non-porous glass is a solid choice for sensitive skin. Shipping: Straight from the US. No messing around. Your search for the perfect blue ends here.
