Set of 3 Piston Fill Waterbrush for Sumi or Chinese Painting, Watercolor or Watersoluble Pencils and Crayons

This are great pens and are enjoyble to use.Timely delivery,and in great shape,no problems noted.

The piston fill is great for traveling and not having to worry about spillage, but the brushes are losing bristles - every brush stroke leaves at least one bristle in the paint -

I am happy with these brushes. It is especially useful when traveling because it's portable. Works wonderfully with watercolor pencil and watercolor crayon projects. Just what I needed.

These brushes are nice for travel because of the filling/draining methods, but you can't leave water in them (say if you were going hiking or on a plane) since the bristles are continuously being fed water (unlike with squeeze-style brushes that have a seal).Plus, the seals aren't great, one of mine is leaking around the edge of the bristle base, and the bristles are falling out like CRAZY. I can't paint with these- there's no sense of control over water flow, the bristle hair is cheap and difficult to control direction, and there are bristle hairs all over my works. I've used them twice since receiving them and am very disappointed. They will stay as a backup plan but I'll never buy these kind again.

These pens was just too intriguing to me. I am so excited to learn about these pens, and incorporate them into use for my paintings.

The caps do not stay on and the brush hairs are coming off the barrel. The water drips or flow with very little control I would not recommend.

These brushes are so clever and I love using them for erasing my water erasable lines on my art work and sewing items. They are great for watercolor also. You do have to condition them to use them.
