Aptly named!

This is not a pen I expected to love as I normally go for more fidget friendly pens, but heard lots of good things so wanted to try it out. It is very aptly named the pocket pro - perfect for the pocket & looks & writes like a pro. Love it in the stonewashed titanium finish which is my favourite. It's super light, a great little size, feels the best in hand of all the Big I pens I've tried to date (having said that have only tried the slim version of the bolt action).. I like that the tip of the pen is that bit thicker making it more comfortable to hold. Writes beautifully & has such a smooth open & close twist mechanism. I have this one & a copper one now & am pretty sure I'll add to the collection. Still love the Bolt Action & the dual side click pens, but for portability & EDC this one is perfect.

Love this sh*t

Love this pen it goes will with my everyday carry and the raw titanium is beautiful!!!

Pocket Pro

I got the pocket pro pen in black and I love it. The size is perfect for EDC, it fits my hand perfectly, and the fit and finish is amazing. I also have the stonewashed bolt action pen which I love also.

dream of a pen stressfull arrival

been wanting this pen for about 3 months and then pulled the trigger with a nice discount code. Live in Southern California and product is shipped 50 miles east from home. Tracking is done via SHOP app. After leaving warehouse tracking showed package in Texas the next day and proceeded to a location in Colorado with my home street name but 2200 miles from home. emailed bigidesign 2x same day to fix and still have not responded. My dopamine rose up when my son came home and handed over the box with my pen inside the day after leaving the warehouse 50 miles from my home.
The pen it self needs to be under 4" in length stowed and exposed I managed to get that with this pen using a shorted Jetsteam 1.0 mm pen refill (cut myself and my fav refill with hybrid gel ballpoint ink). 4" lenngt needed as I edc this in my wallet. Pen writes great as the section of the pen (finger gripping point is about a half inch in Diameter, and can make for an enjoyable writing experience as I have used many gel, rollerball, and ballpoint refills and all can work to make a full size pen or be cut to my needs. I would buy this pen many times over because of the FLEXIBILITY & Simple High quality feel and design

Hey Bryant! Thanks for the review! We did respond to both of your emails. Not sure why they never showed up on your end, it's possible it came through your junk folder. But either way, glad to hear you received the item ok! Let us know if you ever need anything in the future!
