I'm selling this mouse because the size didn't fit my hand, even though I bought a different size from the same manufacturer. It's almost new, only opened. FK1-B(L) https://zowie.benq.com/ja-jp/mouse/fk1-b.html It's in good condition, but it's a used item that has been handled and used by someone. There may be minor scratches, marks, and discoloration that I don't mind. Please ask any questions you have before purchasing to clarify any concerns. The item will be shipped in simple packaging.
