These deep bowls are made of 1.5-mm stainless steel sheet. As the rims are not rolled, the material sheet is made thicker at the rims. The bowls can be easily stacked without any risk of them getting stuck together. The thickness at the bottom of the bowls gives them added stability. They are compact and useful in many kitchen areas due to their small outer diameter. Yet, their volume is greater than their vertical proportions suggest. They are ideal for mixing foods as their gently curved surface makes any ingredient to gather by gravity at the center.
