ZeroShop(TM) Pack of 5, Self Defense Tactical Pen Refills, Replacement Ink (Only Fit the Tactical Pen like the picture)

I ordered my first pen in 2016, and it is still going strong. I ordered a couple of more for the ladies in my life as defensive tools in 2017 and another for my son in October of 2019. The pen's glass-breaker and point both can be effective in stopping a threat, even to the point of lethality. The fillers are quality and write without skipping or jamming until exhasusted. It fits the hand well. Worth several times its price.

Bought these to replace a cartridge for a pen that I bought at a truckstop and accidentally washed. Refill works great, and I couldn't be happier to have my pen back in working condition.

They work alright, size is a little off.

Great price, exact size and fit as described but not as much ink as the more expensive replacements.

The ink writes smoothly and it is a perfect fit for my Uzi pen aka Black Hammer

Went to insert into my tac pen. Something. Broke on the inside of the pen. Now it doesn't work as a pen. It won't open nor close as a pen. I have a no malfunctional pen. Don't get his crap. I'm going to return this crap.

Oh yeah, love my pen and found the right cartridge for it here. I like my tactical pen, I like my tactical pen more with a full cartridge of ink. The price was affordable and good too.

I have two tactical pens which came with not-so-good ink cartridges. They dried up pretty quick. These new ink cartridges are much better than the stock ones. I would buy these again in the future.
