BOSS OC-3 No box Purchased on Mercari about a year and a half ago. However, I hardly used it and kept it "just in case I might use it someday." I probably won't use it, so I'm selling it. The unit itself works without any problems. The appearance is also relatively clean, I think. Please check the photos. Since this is a used item, no claims and no returns are accepted.
