A transparent borosilicate glass cylinder that is more complex and difficult to manufacture thanks to its thermal resistance, thin in thickness but just as resistant as the traditional one. This, together with the marble, creates a set of two objects for the bathroom. One that uses marble or lava stone as a base, ideal for toothbrush holders, and another that uses it as a lid, resulting in a closed container to store all kinds of bathroom utensils. Borosilicate Glass: Cleaning only with soak and water. Brushes with wooden or plastic handles are recommended as they will not scratch or otherwise abrade the glassware's surface. Marble: Avoid abrasives and domestic cleaning materials .
