It works well, but, to be frank, a microplane fine grater is better and easier to clean.
All in one classic Italian grater for parmesan and pecorino Sardo & Romano. Easy to use and perfect to store the cheese cleanly inside the grater. When you want to grate it, simply open the base, grate and close again. Made with hard plastic that make it a resistant and durable product.
Polypropylene is recyclable, has no toxic waste, no toxic emissions, no halogens and no flourocarbens so it is low impact on the environment.
