Security in a Bottle

For the New York–based designer Paul Koh, frequent air travel goes hand in hand with his work. So it is only fitting that he would devise a stylish alternative to the leaky travel bottles that clutter department-store shelves. His pliable blue and white silicone containers pass muster with the Transportation Security Admin­istration’s recent carry-on regulations for liquids; and their wide mouths, thick walls, and precision valves (also found in finer inverted ketchup bottles) help prevent messes.
