It is plastic and metal, dishwasher dishes, offers two cup sizes (gaffe fingers by washing with a sponge against a gaff and protects the tip of the finger, I have made myself) for a maximum diameter usable 55mm (useful for more than carrots and potatoes for small courgettes). Was either spaghettis or fine tagliatelle in terms of size. plastic is strong.
This is a handy little tool.
