New In: Tom Dixon Cog Keyring

Once in a while, you come across something so blatantly useful that you wonder how you'd ever lived without it. That more or less sums up our feelings about the new Cog Keyring from British designer Tom Dixon, recently debuted at Maison & Objet in Paris. It's a sturdy, chic brass keychain inspired by industrial machinery that twists open to reveal a secret compartment inside. Perfect for storing herbs on the go, it's $40 in the shop — and a no-brainer gift for the special smoker in your life.
