Working Condition. The base is uneven, so the abacus will wobble a little; to remedy this, just place a soft cloth or felt on the underside. Fine scratches, wears, and discoloration on wood. Some beads have fine hairlines and wood rots -- they still work and click nicely. Total 15 column (metal rods), with 1:5 beads setup. Circa: 20th century, Japan.
Faint wood smell, with light dust or residue inside. Smoke and pet free environment.
