"Hand me the Prosecco and Watch me get Fabulous" - my kind of water cup! We all know that we should be drinking lots of water, but it's sometimes easier said than done. With these fab LED cups, you'll have no excuse. OK, so I didn't notice that these cups lit up until they arrived! But with a wee on/off button on the bottom and replaceable LR44 batteries, it gives your water a much classier taste!
