Kalita K-2 Copper Coffee Mill - Hand Grinder Made of copper, it has a solid weight and was easy to grind with. I used it only once when I purchased it, and it has been stored at home since then. As it is made of copper, there is some verdigris from aging, but the inside is in good condition, I think. It is now a discontinued product, so I would like to sell it to someone who is looking for one. It's also cute as interior decoration♪
