Thickness: 2.8 - 3 millimeters. (Products are produced by the pouring method and thus there is no clear thickness. Thickness can be tolerated between 2.8-3mm.) Color: Transparent (like glass) The Clear Measurement section is there to cut the products to the size you want. For example, you need a piece of 53x53cm - just buy 55x55cm and write 53x53cm in the net measurement section. If you buy 50x50cm and want a larger size - it will be sent as 50x50cm. For various thicknesses and all your questions, you can contact us via the Ask a Question to the Store section.
