The Neck Hair Guide

The Neck Hair Guide is a piece of plastic that you strap to your neck to cut your neck-hair straight across, by yourself. It costs $9.99. If you can’t tell if you’re cutting your neck-hair straight across, you won’t be able to see if the Neck Hair Guide is crooked, either.

It is, surprisingly, not by the makers of GoateeSaver, the goatee template you bite to hold on your face while you shave around your goatee.
