Good Idea!

Lightweight, flexible, unbreakable, microwaveable and they nest as well! These are a great addition to my kitchen. I haven’t used my other measures and cups since these arrived. Love them.

I love these silicone measuring cups. I do not have to worry about breaking them. They are also easy to pour out of. I did put mine in the dishwasher on the upper rack. They spotted alot. I will probably make sure I dry these by hand real good in the future.


Bye Bye Glass Measuring cups

So pleased with these cups. My favorite feature is being able to flex the cups to increase or decrease the flow of liquid or batter.

I’m so glad I found these! They take up much less space in the cabinet and I don’t need a funnel! Equals more space in the cabinet! A total win for me!

Easy to use and clean. Can always find the right size cup to use. Don’t break or get greasy after being in the dishwasher. Very satisfied.


Great measures

I use these nearly everyday. So much easier to use than Pyrex measures.


Not a necessity, but....

I absolutely love this 3-nested set. So easy to use in many situations. Worth the splurge on my budget!

Measuring Cup Makeover

If you rarely come out of a cooking experience unscathed, these flexible measuring cups are just what the baker ordered.

They’re made of food-safe bendable silicone. Here’s why that’s so nifty: you can pinch the rim to form a spout, then pour with total precision. It makes less mess, particularly when you’re pouring directly into a narrow space, like a food processor chute. And their rubbery texture is easy to grip, too.

These moldable measuring cups are designed to handle any temperature—from boiling hot liquids to ice-cold water. The outside stays safe to touch.

Another benefit to the
silicone design—it won’t break down in heat or react with certain foods.

From amateur bakers to everyday cooks, these cups make measuring, pouring, and prepping a piece of cake.
