I love these mixing bowls.They are just the right size for my needs, not as heavy as some glass mixing bowls however they are completely suitable for any kitchen. The lids fit perfectly and give a good grip! I like the rigidity and that they are microwave and freezer safe. Combined with the shape of the bowls, the material is really good for mixing because it minimizes sticking to the sides. Sturdy, easy to clean! I highly recommend them.
