I have two insulin pens One is a half-unit pen Its name is NovoPen Echo pen It's special because: • It gives doses in half units (0.5) — important for children and precise doses • It has a memory that records the last dose and its time • Designed for small hands and easy to press It is also suitable for those who want to fill it with Exubera It is also suitable for adults The second pen, the blue one Is an empty insulin pen from Lilly It is also suitable for those who need to fill it with Novo or Exubera or others I haven't set a price, but both are expensive And the half-unit one is very necessary for children with low doses Or also for regulation I hope only serious buyers will contact me I will ship it to your area if you are far away via a shipping company
