In 2015 I wanted all Luftverk throws to use Kitty string, but at the time it was hard to get and always out of stock. When this 2021 version came out, they had a bunch of stock and figured I might as well retail this. Going forward this is the string that is included in all Luftverk yoyos, if you would like to purchase some with your order, here is your chance.
The primary purposes to stock this string is so I can have stock of it to include with yoyos. This is the 2021 version of Kitty FAT, available in Yellow or White.
