Query: Buyer Beware

Do not waste your money on these measuring cups. The size of the cup is written on a brightly colored dot on the handle of each cup which is very nice BUT it promptly washes off after just a couple of times in the sink. Mine have never seen the inside of a dishwasher and did not last for more than a month. A very disappointing purchase!
