I have been wanting to stretch my labret for many years, I bought a cheap labret stretching kit elsewhere, the plugs were horrible, uncomfortable and painful to wear. I purchased a few different sizes of these plugs to continue stretching. The quality of these plugs are amazing, wearing these plug, I easily forget that I have anything in my lip as they are so comfortable and light. I'm currently at 5.5mm, I've got a 6mm plug ready to upsize to my goal of 6mm soon, the only issue I have is that Stonewolf make so many nice labret plugs, that I may have to stretch to 8mm as I love some of the ovals that Russell makes. If anyone wants to stretch their labret, buy these or the labret stretching kit, you won't be disappointed.
