Does anyone know if the 500ml bottles of bath soak are in glass or plastic bottles? Can't see any reference to it on the page and don't want to order without knowing. Links here [[https://www.thewhitecompany.com/uk/Nourish-Bath-Soak/p/SNDBS?swatch=No%20Colour nourish bath soak]] and [[https://www.thewhitecompany.com/uk/Spa-Restore-Muscle-Soak/p/A03649?swatch=No%20Colour spa restore muscle soak.]] Thanks!
