After months and months of testing, Big Ace Micro finally went into mass production. This is exactly the same string as Big Ace, but it is offered in a new metallic silver color and in a thin diameter of 1.15mm.

During the production procedure, the manufacturer carefully observed every detail to make sure that this new "micro" string will stay durable and will not lose any characteristics of Big Ace.

This string provides excellent access to spin. Power is elevated and control is right on target. This is one of the most playable polyester that is currently available on the market today.
