This is a stainless steel digital kitchen scale. It has a Z/T ON/OFF button and a UNIT button, allowing for simple operation. It can be used for various purposes such as cooking, baking, and weighing mail. Only the current item is available; there are no instructions. It measures in 1-gram increments, up to 5,000 grams. It works without any problems, but it has been used, so please be aware of that. Requires two AAA batteries. Batteries are not included. Thank you.
