Models adhering to wall-mounted display boards

摘要

Models for educational purposes, which adhere to any wall-mounted display boards, even blackboards, have adhesive surfaces made of moisture-retaining material. They can be moved back and forth on the wall-mounted display boards and be removed and placed on again many times without losing their adhesion. They can also be placed one above the other and displaced relative to one another. It is possible to write on them and they may be of flat or relief-type construction.
