These are fantastic! We were given some a few months back, and bath time has been so fun. They come in primary colours, but they mix, so if you put in blue and yellow you get a fantastic green bath etc. Lovely bright colours.
Spotted that they are currently reduced, so thought I'd mention it for anyone looking for a last minute buy :)
