Elongating kit for 1 pair of ski poles

You can make your pole longer by inserting the "elongating device".  You can remove the handle and then apply hot melt glue and insert the "elongating device".  If you want to make your pole 5 cm longer - you saw off 3 cm from the top of the pole and glue the "elongating device which adds 8 cm.  and "hey presto" you have a pole 5 cm longer!  You have great freedom to experiment and many skiers these days wants longer poles, now that double poling has become the technique of preference for both rollerskiers and snow skiers alike.
