Really great little letter scale that you can easily carry around with everywhere, as long as you need it. It has the dimensions of 12.5 x just under 8 cm. They simply work together. The display is easy to read, batteries are included. The weighing is very accurate and possible even in 0.1 gram increments. It turns also quickly when not in use on its own, so that batteries can be saved. We have paid the balance of a pharmacist and the joy was great. The price is amazing and you get a very accurate and nice-looking scales.
