This one appears identical to the basic V1 that a decent seller would offer, so I'm not about to go through that whole marketing page to learn anything.
I wonder if anyone else is familiar with this pen gadget from a firm in Denmark. It addresses my concerns about contaminated or unclean cartridges made overseas. The makers carry official clearances from regulatory bodies. Their design uses swappable cartridges holding a hundred doses. Still I haven't located anywhere that offers it for purchase.
