How to prepare a 15mg refill
what you will receive
Remove old cartridge, insert new 15mg cartridge into cartridge holder and re assemble your pen *do this over carpet to avoid breakage)
Hold pen upright and turn the dial 60 times (all the way) and push 60 clicks all the way down needle on to let the air escape
Notice the stopper is pushing the liquid up
Once you have pushed 120 clicks out (2X60) proceed to push air out in lower amounts 5clicks at a time, once the liquid reaches the top of the pen and starts drizzling out you have successfully pushed out all the air of a 15mg cartridge and is ready to use
We make things that work better and last longer.
