Broken USB light (Stirchley, B30)

Hi, I have a small globe that can be plugged into a USB port and changes colour. However, it doesnt work. I have tried to open the bottom but the screws have eroded. So, if anyone fancies a go at opening it or just likes the look of it without it being lit up, Please get in touch. The base is nearly 7cm in diameter.
Thank you
