We are envisioning these little measuring cups everywhere. Kids will want to play with them, we want to use them in the kitchen, the play kitchen is calling out for its own set and they are pretty enough to display in a child's room.
The six cup set designed by Carl Mitsch for Fred & Friends is made of heavy duty, food safe plastic. Get them in white or snag the limited edition red set. Fred & Friends has a number of other cute and equally adorable matryoshka kitchen items including measuring spoons, food storage containers and babushkups (nesting drinking glasses).

Have them - love them, use them a lot!
My SIL has a set in her kitchen, I was JUST thinking about getting a set for my daughter to use as a nesting toy...
I bought these for my sister last Christmas. They're cute, but they are more flimsy than I expected.
I received a set as a gift, and while I love nesting dolls, my two young boys play with these. I've never used them as measuring cups and I don't think the top halves would actually stand up very well on their own. But they are so cute!
@zwizh I bought them for my sister last christmas as well! Very funny seeing them pop up here
These are adorable! I bought a few sets on Amazon last year and gave them as Christmas gifts. I found these robot measuring cups and will be giving them to my bachelor brother this year

I have a set of these (from Amazon). They sit happily on my kitchen windowsill, but I still end up grabbing the old faithful metal set when I'm cooking. Maybe I'll give them to my girls to play with in their little kitchen.
I received a set for Christmas last year (popular gift!). My daughter uses them when she helps me bake, and it also helps her make sense of the different measurements (i.e. 1 cup is larger than 3/4 cup, etc.). Love them!
I have these and don't find them to be "flimsy" at all. If I had one complaint, I would say that I would like it if the numbers/size of each piece were more clearly marked. It (the number) is slightly raised on the inside of the bottom of each piece but the same color as the cups, white, so can be somewhat harder to see. My set is definitely not flimsy though. I saw the robot ones and thought those did look slightly flimsy. But anyway, I love mine!
