(2) More about seamless ball:
The exclusive technology creates balls as a single unit, not by fusing parts together under old methods. By getting rid of seams, new balls also got rid of unevenness in shape, weight and thickness that prevented a clean and accurate bounce in the past.
New seamless balls have no soft spots. They are tougher, more durable, and consistent all around.
"KINGNIK" has been approved by the ITTF (International Table Tennis Association). New balls formally meet the new regulations for non-celluloid balls, which will officially be used at ITTF-sponsored events around the world.
New balls are made of poly plastic, the new official material for table tennis balls. Traditional balls are made of celluloid and contains components used in dynamite, making them dangerous to produce, to ship and to store. Poly plastic is chemically stable, safe to use and for you to keep at your warehouse or home.
