Kirschbaum Black Shark 200M

The Kirschbaum Black Shark string is a durable monofilament string that retains tension well. The string offers a mix of spin, power and durability. The string features a polyester core, but what’s special about Kirschbaum's version is that it feels softer than other polyester strings. Additionally, the string is made in an octagonal shape, creating high spin potential. The string is available in different thicknesses. The thicker the string, the stronger and firmer it is. Conversely, a thinner string is more elastic and offers more feel and control.
