Durable 13-Column Chinese Abacus

At 28 x 12 x 2 cm (11.02 x 4.72 x 0.79 inches), this abacus offers generous workspace and ergonomic reach. Constructed entirely from solid wood with a silky-smooth surface, it features 13 columns laid out in the standard Chinese format: two beads in the upper deck, five in the lower. Each bead is shaped from polished artificial stone — uniform, rounded, and precisely sized. Reinforcing metal sheets wrap the outer corners and frame edges, preserving shape and appearance over time. Used globally for foundational maths, it remains one of the most effective tools for building fluency in number bonds, carrying, borrowing, and mental strategy development.
