Made of high-grade silicone, these non-stick sets are heat, stain and odor resistant, ideal for your cooking and baking projects. Very easy to use and clean for dessert prep - simply wipe with soapy water and air dry or throw them in your dishwasher. SIZING: While every woman's hand is a little different – some larger overall, some smaller with some fingers thinner and some wider, this set was designed to provide a full range of options for which most of the sizes should accommodate the average women's finger size. This means that depending on your unique finger attributes, it's possible that 1/3 or even 2/3 of the set might not fit you perfectly, but it's nearly 100% likely that at least 33% of the sizes will fit your specific fingers. The reason we provide a wide range of sizes in each set is to ensure that at least 3 of the nine will fit every uniquely beautiful hand among our customer base. Many of our customers find that the entire set fits well on different fingers. If there are some that don't fit perfectly in your set, we'd encourage you to gift them to a friend with similar hobbies, but who might have different sized fingers.
