Diameter of base: 4.7cm Height: 23cm Wooden pepper mill. I bought this as a stylish pepper mill shaped like a bowling pin, but I couldn't figure out how to open it. I don't know how to put the pepper in. As a result, it's been sitting around as an ornament, and I'd like to pass it on to someone who needs it. I don't know how to open it, so I'm looking for someone interested in it as an ornament. Thank you.
