This is a ZWILLING slicer, 23cm. I bought it online, but when I saw it in person, it was larger than I expected, and I haven't had a chance to use it, so it's been sitting unused. It's a new, unused item, but it has been stored by a private individual, so please purchase only if you understand this. If there are no buyers, I plan to give it to an acquaintance.
