These measuring spoons eliminate the need for multiple spoons of varying sizes. One spoon goes up to one teaspoon, and the other goes up to one tablespoon. When you need to use your kitchen space efficiently, this is a great way to solve the storage problem. I love these spoons because they are easy to clean (I just throw them in the dishwasher) and I don't have to dig around for the right size spoons when I'm cooking. I use these for both liquid and dry ingredients and have not had a problem with them in the years that I've used them. The markings are easy to read (even after several years of use and abuse). The little black "slide" parts have grooves for your thumb, which is handy. The slide moves easily but does not flop around, so it's not difficult to accurately measure your ingredients. This product is well-made and definitely helps me keep clutter at a minimum when I'm cooking!
