How many black bears can this pen take down before needing a refill?

2 and half. Got mama and papa bear with the blue and black refills. As I ran out of the complimentary refills, I improvised the handy glass breaker for baby bear. Now I can eat my porridge, do my crosswords and use my new pen. After I order new refills.....

Does this take fisher and rite in rain refills?

Yes - it fits the Fisher Space PR4 ink refill. Rite in the rain refills work too.

Does anyone know what the size of the o rings are ?

Dear Customer, Thank you for your question. The o-rings measure 1/3 inch (0,27) in diameter. Kind regards The Atomic Bear Customer Care Team

Hi! I am sending a video the founder of the company created about taking the pens on planes. The short answer is that there is always the possibility it could be confiscated. https://youtu.be/ySCSvY0OnIk
