When I went to Lush on Oxford Street, I brought a bath bomb named Sakura. It can be purchased from any Lush store at the moment. I brought it because I liked the use of light colours and of course the smell however when I used it, it was not one of the best bath bombs ever. It left the bath smelling good but there was not as much colour as I expected, the bath turned on to be a really light shade of purple.
When using bath bombs, if it is all the same colour (most of it) like above then cut it into pieces for it to last longer.
