+++ AAA Battery Emergency Keyring +++

When you're on the go, batteries can make the difference between light or dark, music or silence, life or death. So be prepared! Through the keyring you have countless storage variants. After properly closing the lid, the container is waterproof! Ideally suited for outdoor activities!

Keyring I used (standard size): Outer diameter ~ 25.2 mm, Inner diameter ~ 21.7 mm

The mounting of the “one” ring could be a bit tricky. And if you worry about the strenght of the connection! I can assure you that if I had pulled a tiny bit more during a stress test, I would have had to change my underpants.

Because I have no own machine, someone is welcome to make a tensile test who has the possibility and the interest. I would be very interested in the result!
