Colorful Signal Flags have multiple meanings that make great conversation and nautical fun for boaters and land-lovers alike. The set of four 14 oz. double-old-fashioned glass tumblers is imprinted with a code flag, D, R, T, and X. Each flag also has an important secondary meaning for ships at sea, which is defined on each glass.

D (Delta): I am maneuvering with difficulty. R (Romeo): You may feel your way past me. T (Tango): Keep clear. X (Xray): Stop carrying out your intentions.
