Dear sir, my husband has dupuytren and we found your website. What we are wondering: are the Genesen  pens in the large treatment plan model M5.2? Thank you for your reply in advance.  Kind regards, Sandra Jansen

Greetings Sandra,

Yes, we sell more Genesen pens than anyone on the internet and they are always the latest model, which is currently M5.2.  TRH
