Alex Wonder Pen




Introduction: Alex Wonder Pen

Having wanted to expand my ink marking tools I decided to buy a brush pen, I bought the Pentel brush pen and tried it out on the Bristol Board I usually work on and it was all good. However, several days later I did a smudge test and behold it smudged the hell out of it, also large areas of black were streaky and not consistent. I realised soon after that the ink was 'india ink like' and not the real deal. I like the way the brush works with the tapering lines and the easy strokes but the ink was useless, what was I going to do. . . except CREATE MY OWN.

Step 1: My Solution

I had a few watercolour water brushes lying around, they are like a regular brush with a hollow handle to put water in and squeezing it pushes water into the bristles. You know the sort of thing. They can be picked up in art stores or online for cheap too.

Begin by acquiring the right materials:
A Watercolour Brush pen (popular brands are the ZIG Watercolour brush)
A paper clip or similar
Piece of paper
Ink pot.


Begin by taking the lid off the pen and unscrewing the handle.

Next you'll want to use the paper clip thing or whatever you can to get the black plug off. (using teeth also work)

Next, unscrew the ink pot then roll the piece of paper up into a funnel and place in the end with one hand, use the other hand to pour the ink into the handle keeping on eye on how quick it fills up. Remove funnel, put in bin.

Reassemble pieces.

Hold it tip down and shake for awhile (approximately 5-10 minutes) until the bristles turn black.

Overall the Pentel brush pen cost me £10 with 4 cartridges, you can pick up the watercolour brush pen and an ink pot for around £5, it doesn't smudge, it's waterproof, it's nice and black AND the ink in the pot is way more than the 4 cartridges combined so it lasts even longer!

    Not as yet! The two I've got are still fine and liquid-y, even after two months or so and with air in the handles.
