Each set of scales ill require 2 x AAA batteries (not included). The outer measurements of these scales are 110x130mm. They come with a hard protective weighing scale shield (remove before using) and handy case that can be upturned and also used as a tray. Please remove any protective film before use to ensure the scales measure accurately. The scales also have a handy counting function (PCS button).

With an intelligent auto shutdown function (that times out after around 2-3 minutes when nothing is being weighed) these scales allow you to measure in grams, ounces, carats, pennyweights (!) and grains (!!).
