Signal flags are used to communicate messages to and from ships. These outdoor flags are crafted from durable nylon material, with extra stitching for long-life usage in marine environments.

Individual Size 0 letters (12" x 15") with header and grommet are stock items. All other sizes, and pennants made with rope and toggle, are made to order items and take 2-3 weeks for delivery.

The nautical code letter J (Juliet) flag by itself indicates "I am on fire and have dangerous cargo on board: keep well clear of me." or "I am leaking dangerous cargo."
