The utility model discloses need not to use the printing ink pen, directly use a stereoplasm pen -holder can be on the blank writing content.
Description
Technical field
The utility model relates to a kind of blank, particularly relates to a kind of inkless writing whiteboard.
Background technology
Blank/blackboard is widely used in classroom or meeting.Blackboard writes with chalk, and blank ink pens is write, and uses ink to write not environmentally, needs to consume a large amount of ink, and once forget that preparing ink pens gives lessons and meeting with regard to impact.
