#2391: Enfilope

I’ve noticed a tendency, during train journeys, for people to file their nails and then act as if the various dusty fragments simply disappear.

In fact, some of them end up adorning the clothes, not to mention lungs, of their fellow passengers.


Today’s invention is a nailfile attached to the inner face of a small envelope.

When you file your nails, the various scrapings end up in the envelope, which can be discarded (or sealed temporarily and retained for next time).
