You can easily buy Novopen or Insupen which are the leading two brands for re-usable Insulin administration devices.
The availability of these products are very rare in normal medical stores and most of them are unable to manage and arrange for delivery of the same.
I have been buying my diabetes-related supplies from clickoncare.com and found Novopen there too.
I trust Novopen and I trust Clickoncare as well. And most importantly, Novopen is not only safe and 100% hygienic but also less painful than needles.
