Review on SCERRING Tunnels Stretching Stainless Expanders by Mallory Roberts

These tunnels are quite strong, all screws are without defects and I had no reaction to ferrous metal. Tip for using screw tunnels: Insert backwards! (If it wasn't already obvious, now it is lol!) The ONLY issue I had was the lack of markings on each individual pair, meaning I had to use my calibration card to measure them a very long time ago and to label. Luckily they are all true to size, but let's see how they feel on my earlobes. Happy stretching!
