If you are looking for a pair of nunchaku for sports, with fast flashy tricks, then this is not the pair for you, as they are more suited to traditional martial arts techniques.They are very slightly narrower than my old standard black pair, but otherwise the dimensions and chain are the same. They are slightly heavier, but weighted nicely. Purple heart wood is the strongest of woods and very hard to work, so it should be difficult to put a dent in then. Although this wood is supposed to be dark purple in colour, these are a chocolate brown, which is slightly disappointing, and I did need to give them a very light sanding as they were a bit rough in places, but overall these are my new favourite pair.
