Legend on the breaker

What's wrong with this picture?

Well after toying around in the cockpit turning breakers on and off, testing the circuits, it turns out that the legend rubs right off. I only pushed these in a few times and bango, legend gone. I am none too happy. These are $20 a piece, FAA approved, blah blah blah. Guess I'll have to find a white marker to fill it back in.

Note. Ever notice Cessna's have white buttons with black legend? Ever notice on those rentals that all the numbers are now hand written in? Well now you know why. Them damn numbers wear right off.
