Pretty much every kitchen needs a colander, but they aren't exactly the easiest thing to store in your kitchen. With the RMDLO strainer though, you can strain and steam at your leisure and then just fold the whole thing up into something about the size of a ruler. As an added advantage, the design can even be pushed together on the sides so you can empty the strainer into a small container without any trouble. The piece will also work as a steamer by simply placing it on top of a bowl of water.
