Standard Soroban (Abacas) / 23 digits [43300]

Ya recibí el producto, muy buen material

High quality materials and outstanding craftsmanship. This is not a toy, but a precisely made analog calculation device intended for a skilled student/operator. I have multiple soroban and this is one of my favorites. As is common with academic soroban used in the Japanese tradition, the columns are closely spaced (slightly over one-half inch apart) for efficiency and speed. Some westerners unfamiliar with soroban may initially feel that the beads are too small or columns too closely spaced. Such perceptions are normal until the user becomse accustomed to speed-focused applications. By then, a larger soroban with more space or bigger beads might feel clumsy or slow. The only potential drawback to this model is that it lacks the "one touch" pushbutton clearing feature, which is an appreciated luxury but not absolutely necessary. Highly recommended for serious students of the Japanese abacus.
