Lowest price on Mercari (as of 2026/01/05) With a bonus! This is a Kensington Slim Blade, a favorite among DTMers. The white color is rare. I bought it new and tried it for a few months, but it didn't stick, so I'm selling it. I was too used to the thumb trackball. It worked without any problems on both my main MacBook and my sub Windows machine. I was also using the Mac's trackpad, so I don't think it's been used that much. I used it in a fixed position, so there are no major scratches. Everything in the pictures is included. I plan to clean it lightly before shipping, so I think the dust in the photos will be removed. [Bonus] I'll also include the carrying case (pic4), which I didn't end up using. Actually, I'll ship it in the carrying case.
