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!

Purpose Bought EDC Cool

So this is the first product I have bought for "EDC Cool". Well not really for EDC Cool. I carried a Cross pen in my pocket for years but I recently found I couldn't get the refill I like (Blue Fine Point) anywhere. I blame President Biden and all who voted for him. Anyway, as I looked around the internet I stabled on a pen that can take a myriad of refills. The Big Idea Design pens. And so far so good! It feels like a fell crafted item, you know, the kind you enjoy having in the hand. It's light and balanced with a smooth rotating action to bring the pen tip in and out. I'm happy I bought it.

Best pens I own. Period.

Well, my first Bigidesign purchase was the Ti Arto EDC, and I absolutely LOVE it. I quickly ordered a stonewashed Ti Pocket Pro, and it instantly became my favorite pen in my entire collection. After that, I again quickly bought the Ti Black DLC and Brass Pocket Pro's and I couldn't be ANY happier. That was going on two years ago and I obviously haven't been interested in ANY other pens (except the new Bigidesign Bolt Action pens hahaha 🤣). So this is a good review almost two years after buying my 4 Bigidesign Ti and brass pens!

Now down to the pen itself, they're simply marvelous. Impeccable craftsmanship as always from Bigidesign, and the pens themselves are beautiful and a true work of art IMO 😎👍 The threads, springs, clip, etc are all very high quality and executed perfectly. Everything is butter smooth. And the black DLC coating is DEFINITELY more durable and scratch resistant than any of the PVD & IP coatings available. Mine has zero scratches after being used pretty hard after the last two years!

I have easily tried over 150+ different refills and I have yet to find one that DOESN'T work with the Ti Pocket Pro's! My favorites are the Energel (.7/1.0mm) (blue/green/red) refills. But I can almost guarantee that any refill you try in these will work!!! And if you want to use the plastic rollerball refills like the Energel and Pilot G2, but want your pen to be smaller/shorter, just cut off a little bit at the top. I've done it a million times because I prefer a shorter pen!!!

They're also obviously very lightweight because of their titanium construction and are VERY easy to write with, whether you're just jotting down some quick notes, writing an essay or journal, or use it ALL day at work for longer periods of time 😃

Overall, just a fantastic writing instrument that is VERY unique and one-of-a-kind because it has the versatility to use whatever refill you like the best. You WON'T find another pen with that ability, and the supreme craftsmanship that is Bigidesign, especially for this price. Its a no brainer! I'll definitely be buying one of their bolt action pens when they're available next year too! Just a fantastic company who makes innovative and high quality products. You can't really get any better than that IMO 😃

So if you want a super versatile pen and you love numerous different types of refills, then look no further than the Bigidesign Ti Arto EDC and Ti Pocket Pro's! You can thank me later! Find a coupon code online and you can save even more!
