Can someone please link the metal pen from AliExpress/Alibaba? I can't find it now. It was called magic tattoo pen or something and was maybe $12-16. Already have the ergo and its great but yes it takes a little bit more push to inject.
Nevermind, that one is 40.
Sterilization is a whole messy process. To be done right involves popping them open and cooking them under pressure and steam.I see a lot of people talking about injection pens, but there is little information about the cartridges. Click on AliExpress and we have these cartridge options available for purchase, but they are not sterile. How do you sterilize this material?
