A wooden abacus, likely used by my grandparents who were in business. It may have been a gift from a regular customer. The craftsmanship is still solid and it appears usable, but it has been left unused for many years and has accumulated a fair amount of dust. I will lightly clean it, but it is recommended for those who do not mind. Width approx. 28.5cm, Height approx. 11cm, Thickness approx. 3.5-4cm Thank you for looking.
