I had some trouble finding threaded tapers that allowed for easy insertion of tunnels afterwards, but I found these and they're exactly what I needed.
I have a nipple ring where over the years I’ve been decreasing the gauge. On my own I got from a 14g to a 10 and was trying to get to an 8g….I kept trying but couldn’t get it in. Purchased this taper that screwed onto the ring and had it in in 5 seconds…if I can find he taper maybe I’ll go to a 6g it was so easy!
Ordered two stretching tunnels and they work great and are a great product.
I did like your product .
