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

Oh man, this is the best pocket pen I have found. I don't carry an Allet wallet, but I have owned them before. Currently I carry a tyvek paper wallet, thin and durable with beautiful artwork. Even though it's a paper wallet and doesn't have a special pocket for a pen, this thing slips in perfectly and stays in place. The pen is just big enough to write with, it is not uncomfortable, but not ideal for long writing sessions. It operates by a simple twist, the barrel is threaded and screwing it in just gradually exposes the ball point. If this could fit a Fisher space pen refill it would be the ultimate pocket writer. I use mine regularly, mainly for signing checks and filing out the odd form. It's hasn't disappointed me yet.

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.

Nice little pen and the included refill is adequate but does NOT take standard D1 refills. The refill barrel on a standard D1 is just so slightly thinner than what the pen requires and slides right out of the pen. It needs a refill thicker than a D1 in order for the “back” of the pen (the part with the twist mechanism) to hold it in place.

This is a lot of money for a tiny pen, but I love how it fits in the wallet. It looks great, is well made, and writes well.

This little pen has been nothing short of AWESOME! I have not used it enough for a refill yet, but it fits my field notes memo pad perfectly that I carry in my back pocket. I also think my hand writing is almost better with his small pen that most standard pens.

Wasn’t sure about this pen at first but had the Allet wallet for a while and thought why not, no regrets at all it’s so great having a pen in your wallet.

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

Fits in my wallet, there when I need it and has not dried out.

Poor quality and certainly doesn’t hold up to the wear and tear of being in a wallet!
