Deep red marbles, an iguana on the card: this Kim'Play bag is called Iguane and holds 21 glass marbles, 20 of 16 mm and one large one of 25 mm. White and amber veins run through the red glass, slightly different in every marble.
What a child does with them is the old game: dig a hollow, take turns aiming, and whoever hits gets to keep. The large 25 mm marble is the shooter you fire with and the one you would rather not lose.
These are real glass marbles, heavy enough to roll straight and to last for years. They come in a bag with an octagonal cardboard header card printed with the contents.
Red marbles are in demand when swapping, so this bag works well as a top-up to an existing collection - and as a small present for a child who has just started playing marbles in the playground.
