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.amynurse said:This one?


Sterilization is a whole messy process. To be done right involves popping them open and cooking them under pressure and steam.Lucasvinia said: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?

I just buy sterilized carts for a few bucks each from EZ Pen or Pepens. So far, so good....stickfigure said:My new process per advice received on Peppys:
'wet' cycle in AliExpress pressure cooker style autoclave, followed by drying for two hours in an oven at 280F. The plunger is then pushed back in through the wrapper.
Then before use the wrapper is removed and the cartridge is sterilized once again with a few cycles in UV-C sterilizer. Might be an overkill, but I store filled cartridges over 28 days, so the extra steps to avoid bacteria don't hurt. I also filter the solution while filling cartridges.
