hi kendama reddit, i'm looking for some advice on how to restring this kendama. i'd like to get it into a condition that i can begin to learn on it as a beginner, but i don't know what a good length or string material would be. it seems like the old string is glued into the cup body and tama. are there other ways to attach?

i assume the kendama around as old as my dad (~60 years?), so if there's any other restoration tips or identification I would love to hear it!
