A baton will need to be purchased or acquired.  Measure the Learner from armpit to the palm of the hand. That is the size baton you need. Star Line batons are the kind you need, as they are weighted correctly and twirl properly.  They are available on Amazon.  https://www.amazon.com/s?k=star+batons&crid=3SJMYTN4L23B8&sprefix=star+batons%2Caps%2C127&ref=nb_sb_noss_2
