These cups are used by my children, actually got 2 packs and gave 1 as a gift to a friend as her daughter loves Robots. Makes a lovely stacking toy!

Looks great and is something different. Goes great along with our voodoo knife holder and rocket cake tins.

Note: Not commonwealth measurements! American “cup” is smaller than ours. Suits our house far more than the russian doll version, but the square cups surprisingly make for messier filling and pouring. Eg. you don't really want to be filling the 1c by scooping it into the flour bin, because the external details have ledges that the flour gets caught on and you have to shake or brush it off to lessen mess when it falls off again. We've taken to filling it with a spoon. It's a great unexpected talking piece on the shelf above the bench, and you can quickly see if a piece is missing and needs to be found and put back. Just debating how much the measurement problem will affect cooking. :-S
