I think I fell in love with this little pen before I even took it out of the box. It was package well and looked so cute. I am a local truck driver and am constantly getting in and out of the truck. I used to keep pens in my back pocket but then I would either sit on them and break them, or they would fall out and I would lose them. I keep this little Field Mouse on a leather cord around my neck. It's always there when I need it. It writes exceptionally well. When I'm waiting to be loaded I use it to write in my journal. I used the ink that came with it but I can't wait to experiment with other inks that I have. I would definitely buy this again!

I love writing and I love enhancing the experience with a beautiful pen. I recently purchased the Lumos and the Wren so that I could write and illustrate my haiku journal. I was so impressed that I immediately purchased the Field Mouse. I now have a tiny pen in my pocket to record my tiny poems whenever inspiration strikes.

I ordered 2 Little Field Mice. I love them. And I got used to holding it right away. It's on my keys so it's constantly with me.

I didn’t think I’d use the field mouse as much as I do,it was bought for when I didn’t think I needed a pen but it’s quickly become my go to,with it being so small it’s very easy to carry (hide) the ink seems to last longer than you’d imagine,being brass it’s now getting a lovely patina and it’s not difficult to write with either one soon gets used to it’s size,l would totally recommend anyone thinking about it to just get one,I’ve put a tiny lanyard on mine with a small clip so you can literally put it anywhere either on your person or in a bag,love it to bits,thank you Tom it’s a masterstroke

I got the all brass version, to accompany my brass Wren, and it's such a fun little fidget pen! I thought it might be a bit difficult to hold and write with because of the size, but the weight makes it actually pretty easy to do. I keep finding absolute nonsense to write down, just to have an excuse to pick it up and use it!

The Field Mouse is just the right size to carry with you regularly in case you find yourself needing to quickly jot something down, be it anything from a note or phone number to a short speech or poem. It's sturdily built, it feels smooth when put to paper, and it's reasonably comfortable to hold for short sessions. It won't replace your desk pen since it's not balanced comfortably for writing over long sessions, but it'll likely encourage you to leave your desk pen at home.

I got the brass Field Mouse for its heavier weight over other Field Mice and to match a Brass Wren should I decide to get one, which I likely will since I'm impressed by both the Field Mouse and the care taken by Tom's Studio. The complimentary (or complementary?) "Choccy Bickie" Tea I received with my pen helped inspire the pictured poem I wrote, which I used as a chance to test out the pen and the ink it came with. The pen, ink, and tea all impressed me, as did the quick shipping time to where I live on Canada's West Coast, so I'll definitely recommend Tom's Studio and the Field Mouse to others, and I'll likely order from Tom's Studio again in the near future!

Every Autumn I catch intruding mice that invade my house, but THIS year one little Field Mouse caught my heart, and it’s a keeper! Thanks for making pens that will last FOREVER! Perfect form and perfect function. You’re hearing that from a 71 year old Graphic Designer and total detail freak! Congratulations on a fabulous venture. No question what I gave myself for Christmas this year!

My little Fieldmouse is living now with me in Switzerland and enjoys being on the road all over this beautiful country :) We are already bff and don‘t want to miss each other!

I wanted to love it, but the stainless steel is just too slippery. It makes this tiny pen impossible to hold, let alone hold comfortably. It's a real disappointment. If the field mouse had been made of titanium, which has grip, i think it would be great. My Lumos mini in titanium rocks! Tom and the rest of the gang: I love your stuff; I own multiple pens of yours — but the field mouse in stainless is a miss for me.

This pen is amazing and I'm not ashamed to admit I got one in every color. Works similar to the Lumos with it's capillary action. It writes beatifully and for such a little thing, it feels solid in your hand. Curious to know if the other writing nibs would work? Or even the fineliner tips? Can't wait to see how they hold up 🧡

I love it so much and I use at work with field mouse pen it useful thanks 👌🏼

I love this pen. To be fair, I love all of Tom’s pens, I have the Wren and two Lumos Duos. But the Fieldmouse is really special. It’s teeny tiny and it’s sleek and it writes beautifully. Like all of the pens it has a nice heft to it and is well crafted. I use it for writing in my journal and I carry it everywhere. Well done you.

Brilliant finally can use for work, attached to lanyard.. only problem is it’s very small, make it a bit difficult to hold and write with. it would be better if same length as wren to make easier to write with.

Great size for handbag but quality of strap disappointing.

What a delightful little pen. I just received it yesterday and I’m completely fascinated by the level of thought and attention to detail. The cap with an attachment for a key ring means I may never find myself without a pen again. The cap tapers to a flat edge that worked like a charm to open and close the ink reservoir on the other end (I didn’t notice this at first and used a flathead screwdriver, but it’s handy to have the cap for future refills!) The ink reservoir fits neatly into the end cap to prevent getting ink on your fingers while filling it. The tip is smooth, and for a pen that’s no longer than my thumb, it’s surprisingly easy to write with. The engineering has simply delighted me.

I am constantly leaving pens behind and needing them later, and having one so small that it can fit on my keychain gives me a fighting chance when an odd idea strikes. (For size comparison, the pink and green circle in the photo is an AirTag.) Well done, Tom’s Studio. This is another winner.

I adore my field mouse. Cutest pen ever and the fact it's so tiny yet super functional is amazing. I love getting it out and seeing the look on a person's face when I actually sign my name with it, priceless 🥰
Fast shipping and great packaging. Could not recommend enough. Very enjoyable

love the colour anf perfect to use when out and about

love this little pen, its the best to have with on when you really need to write something down when out and about

The Field Mouse – refillable travel pen

I am often caught without a pen, searching pockets desperately. Not anymore! My Field Mouse resides on my key chain, which I almost always bring. So I can now do impromptu sketches and notes on the go! And I have spare reservoirs in case I want to switch ink colour.

This is the smoothest writing pen ever. The only whoopsies I made was I spilled the ink jar and it was so messy. You think there’s another way like a safe dropper? I still have the ink in my hands😂

So pleased with my purchase of a field mouse! It hangs on my keyring, attached to my handbag, and is just the most useful, beautiful pen I’ve ever owned…I’ve popped the wren onto my wish list for when people ask me for present ideas!😊

The Field Mouse – refillable travel pen

Very special little pen! I love my Tom’s pens so much! I dont want to write with anything else!

This the nicest little pen, fits perfect on my name badge when im at work. Keeps a pen always handy now, no matter where I'm at. Love that it is refillable. Love the replaceable nibs and reservoirs.
