Approximately 3/8" long with a 5/16" wearable.
These tunnels are pretty neat. They look like an acrylic double flared eyelet, except one end unscrews (internally threaded) to make it easier to wear.

I kind of feel like these eyelets were a waste since you can hardly see through them at smaller sizes but I'd still say that they're pretty decent

These are great for every day wear. After wearing double flares these can actually be slipped in an out without unscrewing them which is handy.

its rather small at this size and a little fiddly, but it is possible to screw it in and it's very comfortable to wear!

I like how easily it blends in. Perfect to use at work when you don't want it to be seen.
