Can you help me? Can you tell me if mine are Shureido Nunchaku? Bought two in a martial arts shop (he had them in store for a long time), paid 60€ each and every section is long 13 1/4” Thank you! https://www.dropbox.com/s/ryf15opo5phdv05/Foto%2007-02-19%2C%2022%2051%2004.jpg?dl=0 https://www.dropbox.com/s/rbczdyyelco2wgq/Foto%2007-02-19%2C%2022%2051%2041.jpg?dl=0 https://www.dropbox.com/s/w2zj5v6i99l4x8u/Foto%2009-02-19%2C%2007%2001%2052.jpg?dl=0 https://www.dropbox.com/s/0ors3fgz5vmj886/Foto%2009-02-19%2C%2007%2002%2044.jpg?dl=0

I have bought two nunchakus in a martial arts shop (he had them in store for a long time) but I don’t know the brand, they look to be Shureido, what do you think? Paid 60€ each and every section is long 13 1/4” https://www.dropbox.com/s/ryf15opo5phdv05/Foto%2007-02-19%2C%2022%2051%2004.jpg?dl=0 https://www.dropbox.com/s/rbczdyyelco2wgq/Foto%2007-02-19%2C%2022%2051%2041.jpg?dl=0 https://www.dropbox.com/s/w2zj5v6i99l4x8u/Foto%2009-02-19%2C%2007%2001%2052.jpg?dl=0 https://www.dropbox.com/s/0ors3fgz5vmj886/Foto%2009-02-19%2C%2007%2002%2044.jpg?dl=0
