This is a November 2020 shipment of wheels from Nidec-Shimpo of Japan. Although a large company, making drive mechanisms for many types of heavy equipment, they apply their technology to potter's wheels as a matter of pride in a country that reveres pottery in its culture. We have opened every box to reveal the serial number. A certified inspector will check each and affix another sticker to assure they meet CSA Code SPE-1000 for electrical safety. This approval enables the sale of the equipment to public institutions. And it assures you that the equipment meets CSA electrical standards and is safe and insurable for use at home. Wheels like these can last a lifetime. These are very difficult to find for sale as used. Where they are, it is not uncommon to see them sold for more than what was paid new. Within a week we sold 90 of these!
