Size: Diameter 10.7cm POLEX Grater. Because it uses ceramic, there is no metallic smell that you might feel when grating with metal, so it doesn't spoil the flavor of the food itself. I haven't used it for several years and it's been stored away in a cupboard. I no longer have the opportunity to use it, so I would be happy to pass it on to someone who will. Please understand that this item has been stored in a private home for a long time and has been inspected by an amateur. Thank you. *Please note that this item is also listed on other sites, so it may become out of stock.
