Sales have been "better than anticipated," according to a Casio representative. Demand comes mainly from businesspeople giving the calculators as gifts, but accountants use them as well, the company said. The announcement of the limited lacquer edition has spurred overall sales of the S100X to rise by 50%. This is not Casio's first foray into design-conscious products to be given as gifts. In January, it released a special edition of another calculator featuring famed prints from the "Thirty-Six Views of Mount Fuji" series by woodblock master Katsushika Hokusai, geared toward foreign tourists. While the 5,500 yen price tag on Casio's online store is high for a regular calculator, in the first month after its release the woodblock edition sold around twice as many units as the base edition. The image seamlessly covers the tops of the keys as well, which the company says was a challenge.
