This set includes 12 spinner arrows in 4 vibrant colors: red, yellow, green, and blue, with 3 arrows per color. Each arrow features a classic pointed tail design rather than a rounded one. The arrows measure 4 inches in length, making them compatible with standard spinner bases. For installation, a 3/8-inch diameter hole is required. The spinners are easy to install and operate, suitable for gameplay, replacements, or DIY projects. They serve multiple purposes, including use in board games, roulette wheels, educational tools, math aids, and decorative applications. The set accommodates up to 4 players with distinct colors for easy identification.
