Slip holder with cover, Soroban/Abacus and Calculator Proficiency Test
Product Details
My child used this calculator for the abacus certification exam. I'm listing it because it still seems usable. It can also be used for abacus practice.
There was a name written on it, but it couldn't be completely erased. I will wipe it as clean as possible before shipping.

Daily Cleaning: Use a soft brush or damp cloth to gently wipe away dirt. Avoid harsh chemicals. For mesh areas, use diluted mild detergent and a soft brush.
Drying: Air dry in a cool, shaded place after cleaning. Avoid direct sunlight or high heat, which can cause fading and glue deterioration.
