Size is as-packaged, or the diameter of loose marbles. ("D" is the diameter of round items other than marbles.)
These striking marbles have a solid black base with opaque red and white patches. They have a finely weathered finish - frosty, yet smooth - as if they spent years in the sea. This makes them slightly easier to control in a game. 25 glass marbles (one of them is a 1" shooter!) come in a net bag with colorful printed header card. The card includes rules to play marbles on the back, and fun facts about pirates inside! Don't forget something to keep the marbles in!
