Purchased a few years ago and only used once or twice. No instruction manual or packaging is included (the manual can be viewed online). It's compact and fits very well in the hand. I'm selling it because it's not the color I originally wanted, and I've purchased another mouse. 【Design】 This mouse features a simple and refined Japanese design. It will match any desk environment. 【Functionality】 Equipped with an ON/OFF switch, you can easily turn off the power when not in use. This helps save battery life. 【Brand Features】 TIPSAIR offers products that combine ease of use and design. This mouse is an example of that, providing a comfortable operating experience. - Brand: TIPSAIR - Model Number: M-TP10BB BK - Design: Japanese Design - Country of Manufacture: China - Switch: ON/OFF switch Thank you for viewing.
