Review on 🥄 Welcome Industries Visual Measuring Cups: Nesting, Shatterproof, Dishwasher Safe. BPA Free, Made in USA. Ideal for Cooking, Baking with Kids & Learning Fractions by Leslie Smith

I think it's a very nice idea, but poorly implemented. At first the cups seem to stick together. Although they are nested inside each other, putting something on top of the nested cups will require some force to separate them. But the worst design flaw is that the quarter and third shells don't stand upright. When empty, they rest on the handle. Now if you pour some liquid in it it will sit flat, but what if I'm measuring something very light? I only get nervous using it to measure something that isn't liquid. I hope they can improve the design because I really like the aesthetic.
