My good friend introduced me to the Akashiya Sai Watercolor Brush Pens when she brought an assortment home from Japan. I ordered several individual colors to try them out myself and loved them so much I went ahead and got a full set of 20 colors ($34.50). The pens originally came in reusable plastic package but I like keeping them in a jar where they are easier to access quickly. These brush pens feature a filament brush tip that behaves more like a real paintbrush than other felt tip brush pens. This creates a finer point and greater line variation.
The colors are both vivid and unusual like a bright, pastel sky blue and a more traditional artist-based yellow ochre. There’s a super pale apricot color that is fun to use for blending and a indigo-like midnight blue that I love. The 20-color set provides a wide variety of color options and I didn’t feel like any color was missing from the spectrum.
Colors can be altered, lightened or blended with water or each other to create more colors. I tested these pens on my standard Rhodia pad but on a watercolor stock, the inks could probably be manipulated and modified to greater effect.
Individual Sai Watercolor pens can be purchased for $3.50 each. There is also an assortment of pigment, waterproof “liner” brushes that can be used in combination with the watercolor brushes. The liner brushes sell for $5.25 each or a 5-color set for $24.75.
If you’re looking for a brush pen that can be used for calligraphy or art-making, these are totally worth the price.
