levemir

Not sure if this is a flex touch, it just says “flex pen”

I thought Levemir was manufactured by NovoNordisk so you can use the NovoPen Echos with Levemir.
A very quick Google shows the single use pens used for Levemir are called FlexPen/FlexTouch Pen but I would always favour the more robust re-usable pens which are better for the environment and take up less space in the fridge.
