Reddit mentions of MUJI Gel Ink Ball Point Pen 0.5mm Black color 10pcs

I like the idea, but make sure you know (a) how much ink cartridge refills cost, (b) whether you'll be willing to pay for them going forward, and (c) how easy they are to obtain. If they're only available online, you may want to buy a few packs with your purchase of the pen so you don't have to worry about additional shipping costs when purchasing later. (Don't go crazy and buy a lifetime supply, though - sometimes they go bad/dry out after a year or two.) My experience with nice stationery and art supplies is that if they're too expensive and/or difficult to obtain, you won't use them for fear of wasting them. So make sure this won't be a problem.

If you can't find a pen you like that meets these requirements, I'd suggest buying a nice writing journal and a pack of several decent-but-not-luxury pens to use in it. (Assuming you want to stay on the writing theme.) I have one of these MUJI pens and it writes quite well.

Another less expensive pen alternative, if you're more of the old-school fountain pen persuasion, would be a stick pen with interchangeable nibs and ink bottle. It's honestly not very practical but it's pretty fun to write with.

It kind of looks like a Muji pen. I can’t find one with an Akita dog, but here’s a link to the [basic pen] (https://www.amazon.com/dp/B00E1IBPGU/ref=cm_sw_r_cp_api_i_pkD-Ab8SE2E1W)
