Personal Reusable Pen Injector - 80 Unit Metal Pen, Plastic Case and 2Pcs 3ml Cartridges (Green)

The 2 3ml cartridges were not included as it says in the item description

This is a precise injector, though there weren't any included instructions. So, if you know how to use it, it's easy; if not take some time to get familiar with it. Dosage is set on the rear dial and application is done by pushing down on the rear actuator. This does come with 2 sterile cartridges, though in my experience, the cartridges are prefilled and sealed. I'm not sure what I would use the empty cartridges for. As stated, this is not a complete kit, it does not include the disposable injectors (needles) that attach to the tip. As a kit, it has no way to administer anything. This may be obvious to those familiar with it and already use such devices. Just something to be aware of if just getting into it. It's not a bad unit and it feels well made. It is easy to set and remove the vials and they do make a good seal initially and during applications.
