Often the label sticker and rubber pads on the bottom of a mouse covers up screws. If you feel around the sticker you will likely feel a depression for a screw hole. Which you will have to pierce to gain access. If that does not get the mouse open. You may have to remove the rubber sliding pads. Which is daunting as they may never stick right again.
