Scents will vary Our bath bombs are very concentrated with colour and provide wonderful bath art. Some float and some sink due to amounts of oil and cocoa butter added, so while they're activating we always suggest holding them to the surface for best bath art. If you decide to hold them, however, it may cause slight skin staining. If this occurs it usually comes off with a quick scrub. All bombs have cocoa butter, so please use caution while entering/exiting the tub. All bombs are tested and passed by us before selling, but please be cautious of the colour if your tub is porous or lacking enamel. We suggest cleaning the tub before using any bath bombs and rinsing your skin after-especially with dark or bright bath bombs.
