Poolroom supplies include cues, which are long sticks used to strike the cue ball in a game of pool. Cues come in a variety of sizes and materials, such as wood, fiberglass, and graphite. They also have different tips, such as leather, plastic, or metal. The shafts of cues can be straight or curved, and they often have decorative designs. Poolroom supplies also include chalk, which is used to increase friction between the cue and the cue ball. Chalk comes in a variety of colors and is applied to the tip of the cue before each shot. Other poolroom supplies include racks, which are used to organize the balls at the start of the game, and table brushes, which are used to clean the table.
