Has anyone here squeezed out liquid from various carts into a syringe or something to see how much they hold exactly?
I am just wondering because the 2 carts that I have actually used are Janty and njoy, and I notice my njoy ones last atleast 2x longer than my Janty. How is this possible if people say the pen carts hold 1ml each?
If you have tried, post what brand and how much you found it held. I am interested to see! thanks
