# I am struggling to tighten the pen enough.

When loading the cartridge, we recommend wearing surgical gloves to give you a better grip. Sometimes, your hands can be sweaty or oily and this will prevent you from being able to tighten the pen enough to pierce the cartridge. When you are loading the cartridge, it is important you twist until you hear the click and then keep turning until fully tightened quickly.
