Great Ideas #2: MUJI Erasable Pen

So here’s one of my pencil case staples, MUJI’s erasable Pen, £2.50:

As you can see, it’s 0.5mm. And the rubber is in the tip of the lid.

How does it work? Nobody knows… Ok, that’s a lie. According to MUJI’s website: “The frictional heat generated by the eraser at the end of the pen erases the ink immediately” so there you go. But I prefer to think it’s magic.

And here it in in action (sorry for the different lighting, I took these later). It erases well, as you can see. You can still see it a bit on the paper, but no more than you would if you were using a pencil.

So why is it better than using a pencil, I hear you ask? Well, it’s not that different I suppose but a few of the things I can think of are:

  • It doesn’t wear down and you don’t have to sharpen it, so it’s a good one to keep in your bag
  • It doesn’t smudge like a pencil would
  • Personally, I use them most for knitting patterns. This is because patterns are usually printed on shiny paper, which you can’t write on with pencil. This pen allows you to tick off where you’ve got to, but then rub it out when you’re finished so the pattern is good as new!

So there you go, this is definitely one of my top products. I know there are plenty of other erasable pens out there but MUJI just somehow make it cooler than the rest.




I have an orange one of these and everyone is so intrigued when I write with it! Unfortunately, though it hasn’t run out, it seemed to have dried up even though the lid has always been on it, but good to know you can still get these as I may have to repurchase!

Someone wrote me a letter with a Pilot Frixion erasable pen and most of the letter was gone by the time it arrived. I don’t know if the jostling in the envelope “frictioned” off the writing, or if it was heat or cold or something else entirely. Not sure if the Muji pen would suffer from the same issues but its something to be on the look out.

    Wow – that’s good to know! I’ll have to do an experiment… Definitely not one for everyday use, but there are times it is useful. Thanks for the heads up!

I read once that Frixion pens are in danger of being banned from use on certain application forms in Japan because of fraud. I like these pens!
