## Questions & Answers

**Q: Compare ink to Jetstream?**
A: Both power tank and jetstream  are what I would consider “premium”  disposable, refillable pens.  Love them both. They both create a predictable, even line. Jetstream ink is a left hander’s dream; it doesn’t smudge. Power Tank ink, on the other hand, does. 

But the Power Tank ink will write on anything. Slick labels that resist Jetstream ink will gladly take up Power Tank ink without smudging. So go figure! 

Off-topic, but I have had the same Power Tank pen in the same car glovebox for the last 4 years, through blazing summer sun and sub freezing temperatures and it writes like it was new.  Would recommend both instead of one pen over the other.

**Q: Is the Uni power tank pen refillable ? Where can I get refill ?**
A: You can get refill cartridges from Amazon. You will have to replace the cartridge as they are pressurized. To me, It is just as cost efficient to purchase a new pen in this case than to order refills

**Q: When you order 5 pens and you only get 1 pens, but they took your money anyway, do you miss the other 4 pens, or nah?**
A: I have ordered these several times and always received 1 SET of 5 pens. If you only received one pen, I would CALL customer service, and Amazon will replace it. If the replaced item is also only 1 pen, somebody has goofed, while supplying the warehouse! (Nobody is perfect!). Call again and explain. They are very nice  and will do what they can to fix the problem. 
These are fantastic pens that will continue writing, even when upside down!  We love them.

**Q: do you have to pump it up with air?**
A: no, it is already under pressure and sealed ,you just use it
