The original Margrethe bowls were designed by Swedish Prince Sigvard and named after his mother, former queen of Sweden. I'm a big fan despite that they aren't "microwaveable". These new, tiny, colanders are perfect for those of us often preparing small meals and lunchboxes for children. Better yet, they make it easier for our 3-year to drain pasta, or wash ingredients himself. The Margrethe series are produced by Rosti Mepal.
