Magnetic Hat Stash

This is a hat clip style thing at simply slides onto the brim of your hat

With a 1.1 inch wide magnetic disc, it can be used to hold flies while retying on the water, or use it to put extra nuts, bolts, washers, etc.

The specific magnet I used is about 1.1 inches wide and 0.165 inches deep.

Very simple don't overcomplicate it, use however you desire
