(Large) - Tupperware Wonderlier Bowl Set 7.6cm New Colours
Others have commented on the sizes of these bowls, but often with some uncertainty or inconsistency. Tupperware's website says that their capacities are 6 cups (1.4 litre) for the small bowl, 8-3/4 cups (2.1 litre) for the medium bowl, and 12 cups (2.8 litre) for the large bowl. I used a measuring cup to fill them each to the brim with water, and the Tupperware specified capacities are accurate. However, if you fill a bowl to those capacities, you would be hard pressed to put the lid on. I think you need to derate each bowl by at least one or two cups to get a practical capacity. But I will say that nowhere on the bowls is it indicated what their capacity is, and I think that is a major error on Tupperware's part.
Some have commented that these bowls are 'sheer', in the sense that you can see through them. I would disagree. They are not totally opaque, and if you hold them up to a bright light you can sort of see the general level of what is inside, but you certainly cannot see what is in them unless you take off the lids.
The bowl colors are pleasant enough, but somehow they have a cheap look. I think my older bowls had a combination of color and plastic texture that had more appeal than with this set. Tupperware's website lists the colors as Salsa Verde (green salsa) for the small bowl, Tropical Water for the medium bowl (I would have called this 'teal'), and Purple Daisy for the large bowl.
The ergonomics of the bowls is just OK, nothing special. A protruding ridge-ring below the bowl rim gives you a place to hook your fingers under when carrying them. The plastic surface is quite smooth, and would be slippery when the bowls or your hands are wet.
The lids fit VERY tightly, and do indeed seem to be pretty much watertight, at least enough to prevent spills if the bowls tip over, or when transporting liquidy foods in them while driving in your car, or carrying them around. Even though I have experience with other older Tupperware bowls, and their various methods of fitting the lids, I initially had problems getting these lids on. With some other Tupperware bowls, you placed the lid on the rim and pressed down on the center of the lid, and they just snapped into place. On other bowls, you snapped them on at the quadrants using your thumbs. On these bowls, it is more like putting a tire back onto a bicycle rim; start by engaging the lid to the rim at one point, and then use your thumbs to press down firmly as you slide those thumbs along the edges of the rim until they meet again at the opposite side. If you try any other technique, it will seem like the rim will never snap on. In this regard, the small bowl was considerably more difficult for me than the medium and large bowls, probably because the plastic stiffness and thickness is the same, but the curvature is different. I actually thought at first that my small bowl lid was defective, and tried to contact Tupperware for advice; I got nowhere with them, disappointing for what should be a good company. It was another comment on Amazon that led me to the technique that finally worked for these lids. Each lid does have a large tab that you can grab and pull up on to 'break the bead' on the rim, in order to remove the lid. I think it would be difficult to remove these lids by just grabbing the edges with your fingernails.
The Tupperware website says that these bowls are dishwasher safe, but nothing is said about them being microwave safe, and I doubt that they are.
