There are many instances throughout the day when an easily accessible pen can be a big help. Signing a lease? Writing a poem during your lunch break? Composing a grocery list?

Instead of rummaging through your bag for a pen that may or may not be there, meet the Caro Pen— ensuring that no epiphany, good idea, or quick sketch goes unrealized.

The Caro Pen’s cap doubles as a loop that can slide onto your keyring, alongside your keys and any other tools you might use — you'll be equipped, ready to write down that important phone number, even when your phone is dead.
