3 sets Still In Black Booster 125 Tennis String

Description

3 sets of Still In Black Booster tennis string in 16L gauge (1.25mm).
Booster is listed in Still In Black's "stiff" line of monofilament polyester strings, but its playability is quite comfortable and much easier on the arm than most poly strings I've tried.
It maintains a quite nice balance between power and control, making it a great choice for developing players or adults wanting a little more power and comfort while keeping the spin potential of polyester strings.
At less than per set, the value is enormous.
