Magnetic Measuring Cups Set of 7 Stainless Steel Heavy Duty Measuring Cups for Dry & Liquid Ingredients (color)

Are the extra measurement markings on the inside of the cups as well?

Are these magnetic measuring cups dishwasher safe?

What is the product height when stacked? My plastic set which break too easy have a 1 cup that is 2" high & when stacked the handles angle up to 4".

Will the magnet hold them to the refrigerator?
