HexHider Magnetic 3mm Allen Wrench

Handy

This is a great little tool. Works exactly as described snd the manget helps to keep it on the back of my headstock. Highly recommended for people with a floyd rose

I love this thing. I own 4 of them for different guitars. Instead of carrying loose Alan wrench in your case/bag, or drilling a wrench holder into the headstock, they just magnetically attach to the tuning machines. They sit snug too, so you don’t have to worry about them falling off. Only thing I would add would be to make it double sided with the size for intonation as well. Otherwise, they’re great, super convenient.
