The package comes with 2 lashes connected to battery holder and a hair clip to attach to the back of your head. The lashes are reusable too.
Each lash has (12) LEDs mounted to a very flexible 3 wire strip with 3 small wires going back to the control and battery pack. The wires are Y-ed and break out to each eye. Assumingly worn with the wire over the ear.
The battery pack is very tiny, which I was skeptical of the size of the controller when I first saw these come out.
They are powered by a CR1220 button cell battery, which I priced at a local hobby shop for a little over a dollar, but you can buy bulk online for quite a bit cheaper if you're going to be using a lot.
The controller has 7 modes controlled by a push button.

*hold power button for 3 seconds to turn off.
Again, I was skeptical about wearing these on the eyes and having them blink/strobe, but holding up in front of my eyes, the LEDs have a very narrow beam, so you don't get much light shining directly into the eye. And the amount of light output is pretty decent, but hard to say what they would do under direct stage lighting. But for a club atmosphere, they should accent well.
I will of course be using mine under bright stage lighting during a runway show, so we'll see how they read in show conditions and how long they last. So keep watching for those pictures.
From first glance, these are pretty cool little wearables. The price point isn't too outrageous and we'll see how they hold up in a show. As for how they feel, you'll have to ask someone who wears lashes.
I'd recommend giving these a try if that's the look you're going for.
