Can I really take the glass nail file on an airplane in my carry-ons?
I think it depends on different countries and airports that can allow it. However, I think it’s fine to take it. I remember when I was on the Seattle, I decided to pick the same glass nail and you know what? The staff was pretty well, that my face was all around of smile. By the way, I liked that this airport has multiple art installations and exhibits on display and even stores and local souvenir shops. So if you want, you can check seatac airport.
Yes. In fact when we travel to distant art shows our inventory travels with us in our carry-on bags–and we carry hundreds of nail files at a time! Many airport gift shops in the gate area (after the TSA screening stations) carry our nail files–a real boon for travelers whose metal nail files have been confiscated by security screeners.
