I don't know why the Super Medical plugin is not currently available for purchase, but it has been incredibly useful and beneficial for my server. Initially, I had some doubts due to a bug and the developer taking a while to respond. However, the problem was eventually resolved effectively.

  This plugin allows you to create custom meds, event tickets with meds, and much more, limited only by your imagination. It's an essential plugin for any server setup. I hope it becomes available again soon so the excellent work can continue.

Super awesome addon, added a few more skins to allow me to add a few more med pens with diffrent features.
