As it comes to the last gram not with me. But if you really need the 2-gram scale, you have the buttocks card because that is so narrow and small that you ultimately can only guess. Will probably have something to do with the small size of the balance.
The shell is a fine thing, but you can also determine their weight from above reasons not entirely accurate. A tare function does not exist and it is relatively heavy. Since not much is left up to 250g max.
