kleenex has the fugliest tissue box
This is the only tissue box design that has made me seriously consider buying a tissue cozy to get away from its ugliness.
This used to be something only for G-SHOCK watches, but thanks to lovely people with 3D printers, they're now available for a whole bunch of regular Casio models.
It's old, but it works. Mostly.
While I'm happy with my Yamaha Pacifica PAC112VM and it absolutely works for me, it does have a pick guard. Granted, it only covers the middle and neck pickups along with the selector switch, but still, that disqualifies it from the "super easy to maintain" category.
Truly super-easy Strat shape guitars have no pick guard at all because you can access the electronics for maintenance from the rear via small panels, so let's look at those.
This was (and still is) an adventure, and not one I wanted to take.
