The dish is really perfect in itself. I use them as mixing bowl, as dough bowl and the salad bowl. Had she even closed twice, at 50 degrees convection (Attention not above and use bottom heat!) In the oven for faster Hefegehen (fresh yeast) ... is open not optimal because of Zuglust. They can also be tightly, so you can take .. the pasta salad with barbecue / grill for party / birthday party. At last I have in the car no longer afraid that the cover of salad bowl can go up in the curve at the latest! So far, the plastic bowl is also scratch resistant. The last no-name bowl was inside covered with scratches, who (despite 70 degrees dishwasher) immortalized any content at what I found personally very unaesthetic. So strong buy recommendation!
