I received this as a set, but I'm selling it because I already have a set of the same size colanders. I plan to ship it in a custom-fit, minimal-sized cardboard box. The sizes, including the rim, are as follows: 19 cm 22 cm 25 cm New Unused Cooking Utensils Colander Strainer Zaru (colander) Set Sanjo (city in Japan, known for metalworking)
