I just moved to Norway recently from the US to live with my husband and I love to bake. Needed a new set of measuring cups and saw these and instantly wanted them. Besides that I love Fred kitchen items. Fortunately these were given to me as a wedding gift. They are made out of really hard white plastic and are easy to store. I now longer have to tear apart a draw or cabinet to find a certain size measuring cup since they just stack in one another.
