The BPA-free DeltaLight Bowl Sets are lightweight, durable and easy-to-clean. The two bowls are generously deep and the inner and outer bowls are different colours to indicate nesting order. The small set nests inside 1.9L Alpha and Sigma Pots or outside the 1.2L size. The large set nests inside our 2.7L pots. These bowls are made from BPA-free glass reinforced polypropylene, making them easy to clean and microwave safe. The tall, vertical side walls help to minimise spills. Volumetric measurements are on the inside of the bowls, and the curvature of the bowls perfectly complements the Delta Spoon to scrape the edges clean. The small set perfectly fits inside the Alpha and Sigma Pot 1.9L, and also fits outside the 1.2L pots or inside the 2.7L and 3.7L pots. The large set perfectly fits inside the Alpha and Sigma Pot 2.7L, and also fits inside the 3.7L pots. The bowls are available in a large size, weighing 143g.
