Although most of Kendama USA's Kendamas ship with a replacement string in the package, sometimes they wear out and you need extras. When re-stringing your Kendama, it is helpful to have a little extra slack so you can tie your knot at your desired length and snip the excess. Because of this, they include a few inches of extra length. They also stiffen the end of all our strings. This makes the re-stringing process easier for you while threading through the small holes.
