What is this tool for?

In the pro tools kit there is a coiled spring wire with a metal cap on one end. What is this tool for? It is not mentioned in the video short.

Yes! I found out too late so I’m glad to help. It holds the loupe against your eye. Just slip it into the springlooking part and wrap the other end around your head. Careful the tip doesn’t break off - it’ll poke!

Ah, very interesting. Thank you!
