I could never use this on my face but I like the clever and practical design of it. "When you detach the razor part of the card, the rest can be used as a mirror, and it will fit snuggly in your wallet. You can even choose how to scent the razor- with mint, sandal, lemon, ocean, and orange on offer." $9.99, 86x54x3 mm (infmetry.com)
This is cool because I think the design is simple. Also this one is very small so you can fold it up and put it in your pocket so it is very convenient. It could be folded up and it could also stand up and put the media player on top! This design could be used in any environment because it is simple and has one color, the color is black so it matches everything.
