Ballpoint Pen Refills Ink for Tactical Pen : Atomic Bear MTP-6, 2cl Direct, TF Takeflight refil, etc - 2.75 in long and thin body refill - black medium 10 Pack

Will snuggly fit the MTP-6 by Atomic Bear. Will also fit other brands like 2cl direct, tk takeflight. Usually, tactical pens with flashlight and multi-tool will require this format. We realized that these refills were not easy to find, so we decided to make ours with the usual Atomic Bear quality.
This pack contains 10 refills and one spare spring. The spring can be lost which makes it really hard if not impossible to write with your pen. These springs are hard to find... so we got your back covered here ;-)
