I have not used this product or even seen one for that matter but it solves the constant problem of not having anywhere to get ski poles/ mallet shafts. The price is $15.99. A little steep when compared to the $4 – $6 some thrift stores charge per used ski pole. But with thrift stores there is still the crossing your fingers that they even have some. Also that they are aluminum, straight, long enough, and not beat up too much. Any way, there was a time when people only played on beater bikes, but now some people are building up new frames for polo. Likewise, players are going to start making mallets out of new shafts.
