they never lose their value ,if kept in nice condition. a fun experience i recommend for any player who likes some variety in playing other instruments,and it helps get the creative juices flowing to pick up a easy playing instrument like this for a bit. cricket is my life. before the cancer, i was happy-go-lucky. i used to think about my career and worry about the future. but post it, my thinking has completely changed. i'm happy to eat and breathe normally. i'm happy to have my life back.
