I got bored with my pick storage at home, and this is the result:

This indicates what´s inside

Inside there is a top layer with 4 picks and place for tension tools

The bottom layer is for picks which I don´t use so often.

The top layer has magnets inlayed so that 4 picks stay in their places firmly. 2 magnets per pick.

And these picks are just to show the measures and function, I´ll do a 4 piece set with this same curly birch.
