Refill for Smooth Gel Ink Ballpoint Pen 0.5 mm

My current favorite ink pen

I love the muji pens. It’s hard to find a nice brown ink pen to write and draw with and this one ticks all the boxes. And the fact that I can use gouache or watercolor over the lines once it’s dried without it smudging makes me very happy.

Great refills!

These are great refills. I have been writing a lot more in recent days so it's good I've got refills to help keep the flow going!

Pen refills are brilliant!

Love the gel pen refills.
