Serious pool players, this Longoni NIR chalk is what the pros use - and for good reason! This isn't your average cheap chalk that crumbles and makes a mess. The formula sticks perfectly to any tip type and spreads evenly for consistent coverage every time. That even application translates to better control and more accurate shots - no more miscues because of spotty chalk coverage. The blue color is vibrant and easy to see on your tip, so you know when you need to re-chalk. This case contains 75 individual chalk cubes, which is enough to last even frequent players quite a while. The quality is premium throughout - developed in Italy by Norditalia Ricambi but made in the USA. Each cube has that perfect texture that grips well without being too hard or too soft. The case size is compact (about 5x5x3 inches) so it stores easily in your pool bag or at your table. Whether you're playing in leagues, tournaments, or just serious about your home game, having quality chalk makes a noticeable difference in your performance. The gross weight is about 3 pounds for the whole case, so you know you're getting substantial product. If you're tired of chalk that dusts up too much or doesn't adhere properly, upgrading to Longoni professional chalk will definitely improve your game. It's one of those small investments that can actually help lower your scores through more consistent performance shot after shot.
