When traveling with an eyelash curler, pack it securely to avoid damaging it or other items in your luggage. If it is a heated eyelash curler, ensure it is securely wrapped and turned off. If you are packing it in your carry-on, ensure it is easily accessible if you need to take it out at the security checkpoint. Also, be aware of liquid or gel items like eyelash glue or makeup, and follow the TSA guidelines for packing liquids and gels.
