The back of these hexa flesh tunnels unscrew for easy insertion. The wearable length for all gauges is about 1/4".
SIZE HELP FOR EYELETS
The wearable area of eyelets and flesh tunnels is the distance between the flares or flare and the o-ring. The gauge is the diameter.
The gauge is the thickness of the jewelry (Usually the thickness of the material the jewelry is made from but may also be the diameter of a plug or eyelet). From 20 gauge to 00 gauge, the smaller the number is, the thicker the jewelry is. After 00 gauge, the diameter of body jewelry is usually measured in fractional inches as shown below; however, some manufacturers make 000 gauge and 0000 gauge jewelry.
I like how these are discreet without being boring and are comfortable and easy to manage, although occasionally one of the threaded ends can fall off. I also like how I can wear a pair of standard earrings through the hole for a more versatile look.
These six sided nuts match my Mountain Hardwear equipment, and a lot of people comment on their uniqueness.
At least in the smaller diameters, the jewelry is okay for an active lifestyle. After a year of continuous wear, my lobe has loosened enough that the jewelry can be pulled completely through with a little effort. Only once has it come out of my ear during sleep and never while running, swimming or climbing.
I find the threads easy to loosen for cleaning and tighten for security. They clean with alcohol and a soft brush in or out of my ears.
Id like to see more color options.

Hubby says the hex is bigger then he was thinking. but loves them anyway. I think they look wonderful. they were easy to put in and the threads matched up without any problems. very smooth no burs or nicks.
These are awesome, I love the fact that only one side screws on. You still need to make sure every now and then, that it still screwed on all the way, I almost lost one sleeping. Since then they have been great! Very easy to clean. Also gotten many compliments and a few do you have a bolt in your ear?
