Stackable hand-carved glass containers with marble top. Glass more complex and difficult to manufacture thanks to its thermal resistance, thin thicknesses but just as resistant as the traditional one. Available in 3 different sizes, ideal for storing spices and grains, it stands out in any kitchen. 3 Containers 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. Volcanic Stone: You can wash the volcanic stone with plenty of water and a bit of dish soap. We recommend that when you use soap you make sure to gobble very well. Remember that the stone absorbs liquids and it is a norm that it becomes dark when using it. Do not use bleach
