Dry erase markers and whiteboard markers are essentially the same thing. Both types of markers are designed for use on whiteboards, which are typically made of a glossy, non-porous surface like melamine or porcelain enamel.
The term "dry erase marker" is often used to refer to a specific brand of markers that use a type of ink that can be easily wiped off of whiteboards with a dry cloth or eraser. However, many other brands of whiteboard markers also use this type of ink and are often referred to as whiteboard markers.
In general, the main difference between dry erase markers and whiteboard markers is the type of ink used. Both types of markers are designed to write smoothly on whiteboards and to be easily erased, but some whiteboard markers may leave behind more residue or "ghosting" than dry erase markers.
Another difference is in the colors available. Dry erase markers typically come in more vibrant colors, including neon and metallic shades, while whiteboard markers often come in more basic colors like black, blue, and red.
Ultimately, whether you choose to use dry erase markers or whiteboard markers will depend on personal preference and the specific needs of your classroom or workplace.
