## Long description

Centrum 15 cm ruler with 3D multiplication table combines a standard metric measuring scale and an integrated 3D-printed multiplication aid in a compact format suitable for school use.

The product is designed for everyday classroom tasks, homework and quick reference when solving arithmetic problems.
Advantages
The ruler provides two functions in one: precise 15 cm metric measurement and an always-available multiplication aid that can be felt and seen, supporting both visual and tactile learners. Its compact size fits easily into pencil cases and school bags, and the transparent design helps align markings with drawing surfaces. The 3D multiplication table is permanently integrated into the ruler surface to ensure durability during regular school use.
