Here are the last two births of Justten.
Sold in 1000 copies, the Kostak is round. To increase control over the ball, its frame is composed of a mixture of several materials such as carbon and fiberglass. Also its outer surface is stiffened with fiberglass and finally, this pala receives in its interior a high density polyethylene foam to increase a little more rigidity. A pala for intermediate players looking to make the least possible mistakes with uncontrolled shots.
The Bruk is the rejuvenated version of the classic JSTN. This pala is water drop shape with a medium balance to overcome all types of shots. What sets it apart from its sister Kostak is its shape as well as its outer surface, made of carbon for the Bruk. The carbon being more flexible, the ball will have more speed out of racket. The foam used, polyethylene. The Bruk will be the good compromise for loving players to control the game, move the opponents on the field, loving the long points, but do not hesitate to try their luck by hitting very hard as soon as the opportunity arises.
