These mini pool balls are absolutely adorable and perfect for kids or as training tools! The set comes with 16 pieces - 15 numbered balls plus one white cue ball, each measuring about 2.5cm in diameter. They're made from durable polyester resin that can handle plenty of impacts and scratches without showing wear. What I really like is how perfectly round and balanced they are - they roll smoothly and true, just like full-sized pool balls. The small size makes them ideal for kids' pool tables or for practicing your shot accuracy if you're working with limited space. They're lightweight and easy to carry around, so you can take them to playrooms, bars, or any recreational setting. The colors are bright and clear, making it easy to distinguish between different balls during play. They've held up really well with my nephews constantly playing with them - no chipping or fading even after months of use. If you're looking for a fun, compact billiard set for children or want some training balls to improve your game in small spaces, these mini pool balls are totally worth getting. They're well-made, durable, and provide hours of entertainment for both kids and adults alike!
