The Vertical Abacus stands tall to transform arithmetic into a mesmerizing wall of color. Ten stainless-steel rods rise 30 cm, each threaded with ten smooth, silent beads in gradient hues that glide effortlessly under fingertip guidance. A laser-engraved base marks units, tens, hundreds and thousands, while hidden magnets let you snap multiple frames together for larger calculations. Crafted from FSC-certified birch and finished with child-safe oils, it mounts on classroom walls or kitchen cabinets, turning every idle moment into a hands-on math lesson. From first sums to budgeting hacks, the Vertical Abacus keeps numbers—and curiosity—perpetually in sight.
