They feature a silver-coloured glass surface that\'s totally flat, food safe and fantastically on-trend. Place your dry ingredients on this shiny surface to weigh them - either loose or in a measuring bowl. Because it\'s stain resistant and easy to wipe clean, you can measure fruits and veggies directly on the surface. For powdered baking ingredients, like flour and sugar? The 17 x 23 cm platform is ideally-sized for bowls and containers. With their tare functionality, you can return the measurement back to zero with the touch of a button. This makes it easy to discount the weight of measuring bowls to weigh just the ingredients you\'ve got in them, or for weighing multiple ingredients in just one bowl.
