Sub Standard
Fat - 100% Polyester
Sub Standard is an entry-level string for beginners and intermediate players who want to start with a low-cost bundle. The sub-standard strings are made from 100% polyester, with all three different types of Normal, Fat, and XL.
Compared to First Class, the raw materials used are a little more inexpensive. However, Kitty guarantees that even with the low-cost price, they still focused on the final quality of the product so that it doesn't feel cheap or is easy to wear out.
FAT
This is the thicker version of Normal at the same time heavy String among Kitty String. This has 12 strands of thread but still makes a good whip and slack. Most slackers like this Type of String. Many yoyo players use this for wide gad yoyo which giving it a more responsive feel, for tight binds (which means your next throw is going to have some intense spin on it).
Strings are between 120 and 125 cm in length, so they are a good choice for those who like longer strings. In anticipation of being cut to a specific length, these strings do not come knotted, so you must tie your own finger hole.
