Colours, scents and textures will vary as they are handmade one at a time Our bath bombs are very concentrated with colour and provide wonderful bath art. ( embed colours will vary)Some float and some sink due to amounts of oil and cocoa butter added, so while they're activating I 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 Fizz Soakery before selling, but please be cautious of the colour if your tub is porous or lacking enamel.
