Food-grade material: The 3.5-quart pasta colander and mixing bowl are both made of 304 stainless steel, a food-grade material that is safe, rust-proof, non-staining, sturdy, and durable enough for daily use. The colander and washing bowl are dishwasher safe, the inside of the bowl is very smooth, so it is easy to keep clean. The mixing bowl is also made of 304 food-grade stainless steel. The inner wall uses mirror polishing technology, which is bright and shiny. The drainage hole is about 2mm in diameter, just right for washing rice, grains, beans, lentils, and would not spill out when rinsing. It drains water quickly and efficiently, and no food will be lost from the stainless steel strainer. When using a colander, there always seems to be water left at the bottom or leaking onto the counter. With this two-piece set, the colander sits in a matching bowl that catches any residual water. The bowl can also be used separately for mixing eggs, dough, and salads.
