Description

Automatic sealing pen

Technical Field

The utility model relates to the technical field of modern stationery, in particular to an automatic sealing pen.

Background

The pens include pencils, pens, ball-point pens, markers, white board pens and the like; the whiteboard marker is a tool for writing on the whiteboard, and is similar to chalk of a blackboard. The pen uses ink as ink, can be written on a smooth white board, and can be erased by a white board eraser. The white board marker contains chemical raw materials and has the taste of the chemical raw materials. After the ink is solidified, a layer of adhesive film is formed on the surface, the adhesive film becomes strip-shaped or block-shaped particles after being wiped, no stain is left on the board or the eraser, and the effect of the adhesive film can be tested by wiping with fingers instead of the eraser during field test.
