What is the meaning of custom, meaning I chose the best parts for the mouse and it's lightweight? Custom mouse Viper mini. The mouse company PMM, if you go search, you'll find their cheapest mouse is 1000. The internal parts are Razer Viper V2 Pro ‏Neo 8k ‏35 g. The coating is ultragrip. The skates are G305 Tiger ICE V2 ‏Razer Hyper polling 8k. Battery 300mAh. And it comes with a bag containing its tools and mouse screws. I ordered the mouse from America and waited two months for it to arrive. Usage period only a week. I bought the mouse for 1330. Reason for selling: its size didn't suit my hand. I ship to any city in the Kingdom. Price 500
