I came across this ‘Travel Hack’ the other day.
The idea is that the Binder Clip protects the razors blades when you are travelling.
Well I don’t know about the blades you buy but the blades I buy come clipped in a plastic box.
When You have finished your shave you can just click them back in the box.
Even if you buy disposable razors they come with a plastic guard you can put back on.
Whichever way you go it will be cheaper, and lighter, than this stupid idea.
