The stockroom sells a few different ones, but not on a string persee , probably due to hygene reasons. you could always buy a set of them, cut the material off in between each ball and dril a small hole in them and use your own string or thin rope. String or even thin rope would deteriorate fast i would think under constant cleaning though.
