Flashing Lights Whiskey Glass

Flashing Lights Whiskey Glass perfect for parties and New Years events. Basically it is just a plastic cup with some LED lights in the bottom, but it works damn well and its very cheap anyway.

The glass has an on/off button so that you can turn the light effect off if you want.  Apparently it lasts quite a few months before the battery goes and it can still be replaced if you really want. The item is simple and works as you would expect.
