What Kitty String say about their Basic String Line:
Basic is our entry-level string for beginners and intermediate players who want to start with a low-cost bundle. The Basic strings are made from 100% polyester and come only in two colors, YELLOW and WHITE, with all three different types of Normal, Fat, and XL available.
Compared to First Class, the raw materials used are a little more inexpensive than we use. However, we guarantee that even with the low-cost price, we still focus on final quality for the product doesn't feel cheap and doesn't easy to wear out.
We integrated the Inverse system into the string, and the length is still 120 to 125 cm long.
