The glitterbomb spheres are non-toxic and phthalate-free and you can wash them with soap and water to keep them clean and smelling fresh :) We recommend airing them out in a well ventilated area which will help dispel the rubbery scent.
Do note, for soft vinyl rubber of this kind, (which the Italian manufacturer, Play juggling, chooses as the best material for contact balls) naturally releases plastic oils as it ages which can make the surface of the sphere feel sticky. If this happens, we recommend wiping down the surface with rubbing alcohol on a rag or paper towel.
Hope that helps, and if you have any questions please contact us at
Happy flowing!
