This would be perfect for using as a stamp with ink or for stamping clay etc.
This stamp is the Kanji (Chinese character) for "枉" "magaru, magerui" = "bent, crooked".
It measures 2.3 cm long (long enough to be able to get a nice grip) and 5mm wide. The Chinese character itself is about 5mm wide....so please note how tiny it is. It is made of metal.
