US Patent 11305576 Multi pen dry erase marker
Article
The multi pen dry erase marker consists of two to six color dry erase pens that are spring loaded into an ergonomic housing and designed to be used with one hand only. Changing of colors is easy to do by pushing a button to add a pen color. To remove a color the pen is pushed back into the housing which locks it back in place. The end cap of the marker has a large felt or sponge tip to easily erase using a standard whiteboard. A storage cap protects the pens from drying out when being stored.
