Because our Eco-Razor blades are so easy to remove, they are not permitted in carry-on luggage with the blade on any flight. They are however fine to pack in your carry-on without the blade. The Transportation Security Administration (TSA) prohibits any item that could be used as a weapon, such as sharp objects, from being brought on board an airplane. Therefore, it is recommended to pack your Minim Eco-Razor in checked luggage.
