This is a set of a RICOH slide rule and a Yamasho triangular scale.
The slide rule comes with a case.
Triangular scale:
Red: 1/100m, 1/200m
Black: 1/300m, 1/400m
Green: 1/500m, 1/600m
These are old items and have scratches and dirt.
I would be happy if someone who needs them could use them.
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.
Storage: Stuff with paper to maintain shape when not in use. Store in a dry, ventilated area to prevent mold. Rotate between multiple pairs to extend lifespan.
Usage Notes: Designed for basketball. Not recommended for hiking, long-distance running, or other specialized sports where different performance features are required.
