Set includes 3 packs Billiard-Prime – these are balls for Russian billiards made of phenol-aldehyde resin and have a quality comparable to industry leader – the Belgian company Saluc S.A. We can safely say this is an exact copy of Aramith Standard . Weight, density, balance, diameter tolerance, sphericity, colour, surface polish and brilliance – that’s all like the balls Aramith has. The pack consists of 15 balls with numbers and a cue ball of 68 mm standard for the Russian pyramid. The extra hard phenolic surface drastically reduces burn spots on both balls and cloth. As a result, balls need to be polished and replaced far less, saving both time and money. Balls for Russian billiards Billiard-Prime – iit’s a good offer in terms of price-quality ratio. Billiard-Prime – the perfect choice for commercial and personal use. Feel free to ask any questions.
