AllettAllett Micro Pen | Slim Wallet Pen, Ballpoint, Stainless Steel & Replaceable Ink Cartridge | Durable & Fits Pocket, Purse, Planner or Passport

So tiny! I love how it fits in my Allett sport wallet—which is also great.

I normally keep a Fisher Space Pen in my pocket wherever I go, but I wanted a slimmer more compact option when I want to go as minimalistic as possible. I got this to fit inside the Allet ID Wallet and it fits in the slot pretty well. This is NOT something that's intended to write for any prolonged period. This micro size pen only works for simple tasks like signatures and maybe short notes. I have about medium sized hands and it is tiny. The photo I posted shows the size in contrast to my Samsung Galaxy Buds.The first pen insert that comes with it works fine for me and actually writes very smoothly. I believe the refill is the D1 size, but I'm not positive on this as I haven't had to replace it yet.Overall it's a decent little pen if you need one in a pinch.

Writing with a smaller pen is quite a bit hard lol, Nice little pen tho

This little guy is really convenient if you have an Allett wallet. It fits right in the little pocket, it's such a game changer for jotting down notes or writing on receipts. The tip twists in so that you don't get ink leaking on you. This pen is terrible for anything longer than 10 minutes of writing so set your expectations there, but it does write decently well.

This pen didn’t survive a single week-long trip abroad in my Allet passport wallet. The lower section that twists to extend/retract the tip will not stay in place, and looks like perhaps it was glued to the inner part it connects to? Seriously bad quality.

This pen has a nice finish, it’s super lightweight and discreet.. fits well inside the allet sport wallet. I haven’t used another pen since this one arrived. You know you always have a pen on you since it fits perfect in the pen slot of the wallet.. you do not feel any bulk to your wallet or pocket at all.. I love the design. I will be buying some ink refills for this one! Another great addition to my edc rotation.

A pen is something you may not need very often, but when you do there's really no substitute–so having one always at hand, without having to carry or keep track of it separately (fits in my wallet), is great. Also, it's quite nicely made for something you're basically meant to forget about. Almost a shame, really!

There are certainly more comfortable pens, that still collapse, out there. But I think this minimizes the size, while still retains usability. It's not something I would use for extended periods, but it's great to slip in the wallet and forget it's there until you need a pen in a snap. and for the price, to me it's a no brainier.
