Who is the Dunlop Black Widow 18G Set best suited for?

Polyester (co-poly) is the choice for advanced players with full swings who want control, spin and durability. It's best suited to mature players - we don't recommend full-bed polyester for juniors or anyone with arm issues.

What does the 1.21 mm gauge mean?

The 1.21 mm indicates the string's thickness. This is a thin gauge, which delivers better spin bite and feel at the cost of slightly shorter life.

What tension should I string it at?

The recommended tension range is 48-55 lbs (22-25 kg). String toward the lower end for more power and arm comfort; higher end for tighter control.

How long will this string last?

This is a durable string that should last most club players 25-40 hours of play or around 2-3 months of regular use before losing pop.
