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

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.

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.

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.

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.

Excellent and convenient. This pain goes best with the song larger wallets I found in the smaller wallets it is uncomfortable and the wallet does not close completely. Most would probably agree that these days we rarely use a pen, but it is so sleek and unobtrusive. I think it’s worth having for the rare occasion.

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.

It works. I wouldn’t want to write an essay with it but for the intended use it is perfect. A++

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