British brand MANTIS entered the tennis market in 2011 and the meticulously crafted rackets are often a popular choice in the tennishead racket reviews.

The MANTIS tennis range also includes strings, grips, bags and balls and we have a case of balls (18 tubes each containing four balls) to give to one lucky reader.

The Tour Balls are ITF approved and great for any type of surface. Like all MANTIS products, the mantra of the company is to produce the best quality products by using quality materials and respected suppliers, and these pressurised balls are made of the highest quality grade of felt available on the market.
