Abstract: A modular writing instrument cap system is disclosed, in which each individual cap comprises an elongated tubular portion having an open end and a closed end. Near the closed end the cap is internally provided with a seal member adapted to seal with a writing instrument holding quick-drying ink. Near the open end, the tubular portion is internally provided with a catch for removably securing the cap on a writing instrument. Externally on the closed end, the cap is provided with a transversely-oriented open ended tubular barrel. The barrel is configured to receive an internally threaded sleeve, terminator rings and screws which thread towards one another through the rings into the opposite ends of the sleeve in order to hold the assembly together and secure a bail to it. The ends of the barrel and corresponding ends of the terminator rings are cooperatively notched to accommodate the legs of the bail.
