Artist's Wall Pen is based on a regular washable marker, but instead of containing watered down ink, it is filled with mainly water and light soap for color.
With the Artist's Wall Pen, your children can draw and be creative without limits, while simultaneously making your house cleaner.
In addition to pushing the users' creativity, they will also learn about cohesive forces between soap water and many different surfaces and textures.
These pens cost around $4 and are very reasonable because they are reusable. They are made out of plastic, making them both durable and safe. There are no sharp pieces and the only movable part is the screw cap used to refill the soap water.
