Lékué Microwave Cookware Red Shallow Steam Case 650ml 5 "Wow it’s unbelievable" Mrs Waddams 03 August 2018 I have never purchased this type of cookwear before because I thought that it would melt in the microwave. What a miracle, well to me it is, I am quite elderly, so cannot cook meals for myself if they are in the oven because I have limited standing time. With these I cook quickly and healthy, as it steams. Great products. I am looking for more now.
