United StatesCatalyst
I use Catalyst string in the mains and I get good spin and control. The Catalyst string is very friendly on my wrists. Great string!
United StatesBest Poly String Ever!!
Tried this string out and was amazed by the spin and bite I would get on the ball. The shaped texture gives it an extra spin that I love. And its a little bit softer of a poly which has been fantastic for my arm. Will definitely be buying again!
United StatesThis string is so awesome!
This string is very nice. The biodegradable statistic I really enjoy, and the fact that it’s eco-friendly is another plus. Will play with these strings for a while!
United StatesGreat string!
I love this string, it’s super soft and great to play with. I love that it is bio degradable, every time I re string my racquet I see how much waste is produced so knowing that it’s more eco friendly than others is great!
United StatesSave the Planet!
I generally don't play with a monofilament string, but this is one of the best playing ones out there, great spin. And even more importantly, it is biodegradable, which means a lot to me. I love supporting businesses that are keeping our planet in mind. Thank you!
