These small Stainless Steel measuring cups come with a metal ring to keep them together. All four of the measuring spoons have their measurements labeled on the handles of each. In addition the measuring cups also have a high polish mirror finished that like the other Heirloom products is designed to last a lifetime. The four measurements are 1 tablespoon, 1 teaspoon, ½ teaspoon, and ¼ teaspoon.
