I purchased this on Kickstarter for the t-shirt. It's a new Lofree mouse. The color is black, and all accessories are included. I only opened the t-shirt, but the back print didn't really suit me, so I'm letting it go. 【Product Specifications】 Length: 121.41mm Width: 62.7mm Height: 37.94mm Weight: 47g ± 2g Shell: ABS + Magnesium Sensor: 3950 DPI: 30,000 IPS: 750 Acceleration: 50g Polling Rate: 8000Hz Connection: 2.4GHz / Bluetooth Main Switch: Kailh White Blade Side Switch: Huano Wheel Switch: Kailh Encoder: Fuhua LOD: 0.7 / 1.0 / 2.0mm Battery: 250mAh
