Ask teachers, what material is this abacus?

The material of this abacus should be rosewood.

Ordinary old abacus is usually made of rosewood, which is fine in structure, hard and heavy, and can sink into water. In addition to being hard, it is dark red with dark brown and black stripes, which are clear and varied.

The ancient abacus was once a must-have item for every family. With the development of the times, it has withdrawn from the historical stage, so keep it for fun.
