Tecnifibre Black Code 4S is a 4 sided version of the extremely popular Tecnifibre black code polyester string.
This plays and feel pretty much like Black Code.
The new 4 sides ( square shape ) allows this string to sit upon each other flat, allowing extremely good sliding and snapping back effect.
Spin and comfort is increased in this new version of black code. Because of its shape, this string does feel somewhat larger then its gauge size.
