Set of 2 Pocket Version Synthetic Piston Brush Pens[Set_of_A10_A20]


 *You may order individually or as a set. Please browse down to fill in the quantity and add to cart.

Our new pocket version has made a number of upgrades and improvements according to user feedback, which include English labels with use instructions, smaller tip for delicate artworks,  and a "stop click" on the metal cap.  





This pocket version piston brush pens are suitable to fill with ink, liquid watercolor or just water. The top of brush handle is a piston knob that controls the piston-filler and adjust the flow while using. The exterior of these brush pens is like a regular fountain pen. The metal cap is now comes with a "stop click" inside to prevent from crashing the brush by over-pushing. The cap may also serve as an extension to the handle, more secure than the original version. Its compact fountain pen design makes it easy to carry around. Great to work with ink, watercolor, half pans, watercolor pencils, soluble crayons, and pastels.   


100% synthetic bristles which simulate natural tips of animal hairs that gives the brush a pointed tip. It will bounce back to its good shape and fit into the metal cap easily. It comes with a piston-filler which you can load with water, liquid watercolor or ink as you prefer. Two brushes are sold in this set:  

1. Synthetic Sheep Hair Brush(A10):


Brush Tip Size: 5/16"(8mm) L, 1/8"(2mm) D; Length(capped): 5 1/2"

Please make sure the glue in the new brush is washed out completely before using. The brush is very easy to clean, just squeeze out some water and brush it on a paper towel.  Main care tip for the water brushes would be to clean and drain them before storing them when they are not going to be used for a while.

Product review:


"The brush pen is really like an actual brush. It feels very much like a natural I mean. It makes amazing accidental flowing lines, and no more worries of being dried out or too much inks flowing because of the piston.  
And the hair tip feels like made with almost full of natural hair that keeps the original shape and sharp point of the tip by smoothness  
And also, it doesn't need any expensive special ink :). Just like an actual brush that I can draw outside too.

This brush pen is very creative, and useful that I would love to recommend to other drawers. You know what? Actually one of my professior who teaches perspective class actually asked me what pen I was using. "
