Packing tweezers for travel requires a focus on both protection of the delicate tips and compliance with aviation security regulations. To prevent the precise, aligned edges from bending or becoming dull, you should always slide on the small plastic protective sleeve that usually comes with high-end tweezers. If you have lost the sleeve, a small piece of a drinking straw or a tiny bit of blue tack can serve as a DIY alternative. For further security, place the tweezers inside a hard-sided manicure kit or a small tin rather than letting them float loosely in a soft makeup bag. Regarding security, the TSA and most international agencies allow tweezers in both carry-on and checked luggage because they are not considered a "bladed" weapon. However, if your tweezers have exceptionally long, needle-sharp points (like specialized splinter tweezers), it is safer to pack them in checked baggage to avoid a manual bag search. Always place them in the center of your bag, surrounded by soft items like clothing, to ensure they aren't crushed by the movement of other luggage during transit.
