This is a set of two large stainless steel colanders, perfect for washing vegetables and fruits. The large size also makes them useful for cooling boiled noodles. The colander with the thicker rim has a mouth diameter of approximately 24cm, a bottom diameter of approximately 13cm, and a depth of approximately 11.5cm. The colander with the thinner rim has a mouth diameter of approximately 25cm, a bottom diameter of approximately 17cm, and a depth of approximately 11.5cm. The latter shows some distortion in the mesh and a little rust at the joints, but the construction is solid and it has been usable. Please check the photos for the rust before considering a purchase.
