Traditionally, code flags or international signal flags are used by ships at sea individually to spell out short messages or in combinations with special meanings. Our code flag bunting includes 40 code flags (letters of the alphabet, numbers 0-10, and three signal flags). Made from colourful, lightweight polyester, it is intended for decorative use around your home, office, garden or boat! Length 50ft (15m); flag sizes vary from 8x5" to 12x5" (20-30cm x 13cm).
