I recently discovered a pack of Aquastroke brush pens in a drawer in my studio. I bought them as an impulse buy about a year ago, but never had the time to really test them out. After some getting used to, I’ve decided they are a great find!The way they work is by storing the water needed for watercolors in a reservoir in the handle of the brush. You fill it up before you go out to paint and then don’t need to bring a container of water with you. While I wouldn’t want to attempt a large painting solely with these, they are perfect for sketching and small studies. They are clean, easy to use, and can replicate closely the effects and feel of painting with a normal brush.
To use them, you fill the reservoir with water and then give it a squeeze to start the flow of water. When the brush tip is wet, dip it into your pigment and start painting. To increase the flow of water, you simply squeeze the handle a bit more. This is perhaps the hardest thing to get used to, but with some practice, it actually becomes quite intuitive. When I change colors, I squeeze the brush into a paper towel to get the excess pigment off, and then just give it a good wipe with the paper towel for good measure.
The brushes come in 4 sizes and brush shapes, my favorite is the medium pointed round because it is similar to the pointed round sable that is my favorite studio brush. I would definitely recommend these for plein air, painting in your mobile studio (car), or for travel sketching.
The brushes can be purchased online from most major retailers, here is a link to the product on the Jerry’s Artarama web site.
