Pool players and billiards enthusiasts, this 40-pack of cue ferrules is perfect for maintaining your equipment or repairing multiple cues! Each ferrule has an outer diameter of 13mm (0.5 inches) and inner diameter of 8mm (0.3 inches), made from durable fiber material that stands up to repeated use. Ferrules are that crucial part between your cue tip and shaft that absorbs impact and protects your cue from damage. Having a supply on hand means you can replace worn ferrules quickly instead of waiting for repairs or buying expensive new cues. Installation is simple - just screw them onto your cue heads when replacing old or damaged ferrules. The fiber material provides good durability while maintaining the right feel and performance. With 40 in the pack, this is great for pool halls, serious players who maintain multiple cues, or anyone who wants to be prepared for when ferrules wear out or crack. They also come in other sizes if 0.5 inches isn't right for your cues. Keeping your equipment in top condition makes a real difference in your game, and having these essential replacement parts on hand saves time and money compared to professional repairs. Seriously, for the price, this 40-pack represents incredible value for anyone serious about maintaining their billiards equipment properly.
