Thank you for your email and information you provided us. However based on the information and sales receipt the date of purchase is 13-Oct-2015 and this case submitted October 17, 2016 and it will not be covered under warranty. I would suggest that you simply purchase a new pen. We do not repair pens as they are replaceable as a whole unit only with the exception of the nibs, rings, grips and rocker switch. And for your pen compatibility reference visit http://www.wacom.com/en-au/comp. And you can check also a online eStore https://store.wacom.sg/Home. Thank you! Have a great day!
