I love my Tombow dual brush pens! The one end is easy to draw with and the colors are vibrant and beautiful. The other end has a brush tip that can be used as is or one can lay down layers of color on a palate and use the brush that is included to create tonal designs full of depth. The gradient effects you can achieve are lovely. Finally, you can mix in a little water and create breathtaking water color designs.
I use these pens to create greeting cards and I love the way I can use them to create depth and variations in colors on the cards. I love the fact that I can use my water brush to draw the colors across the card.
