Steel Blackline® Internally Threaded Thin Edge Tunnel

The Thin Edge Tunnel from the Steel Blackline® range is made of premium quality PVD coated Surgical Stainless Steel and is available in 3mm up to 6mm (in 1mm increments) and then from 8mm up to 40mm (in 2mm increments). They all have an 8mm width. These particular tunnels are not only internally threaded but have a 'slimline' edge, a much thinner rim than normal tunnels.
