Just finished my third time, same cartridge. I will use one a month. It’s totally fine. Also using it on my face. Spray some alcohol on it before and after. Good to go.Well my extra cartridges still haven't arrived. Could get them sometime in december. And I only have 1 cartridge left that I have used once already. Think it's safe to reuse it until it comes or atleast once more, or should I just use my roller?
Just ordered 5 from Germany. hopefully arrives sometime next week. f*****g hell, like 4 euros each.
Man the shipping time from China sucks.
