Cool Tool - Water Brush

Here's a cool tool I picked up recently. It's a water brush.  I holds water which is send down to the brush.  You can then pick up color from a variety of sources and paint with it.

The color can be a watercolor palette, a dye ink pad, liquid acrylic paint, and I'm sure there a many others. They come in several brush tip sizes like small, medium, and large. You squeeze the barrel to get water to the brush. When you want to change color just squeeze a bit of water and press on your cloth or paper towel and you ready for a new color.

Several makers produce these. Pentel, Sakura, Derwent are several. I believe Tim Holtz has a set and Stampin Up as well.
