For draining things that do not fit in the drainer basket or that you want to separate from tableware. I found a useful item at the 100-yen shop "Ceria", so I will introduce it.
Insanely simple drainer item
An item called a "corner drainer tray" that is installed and used at the "corner" of the sink. By placing the two sides of the triangle on the edge of the sink, you can place things on top in a stable manner.
Can be installed at the corner of the sink
Convenient for draining empty containers and washed vegetables as well as tableware and cooking utensils. People who have triangular corners can also make effective use of the upper space.
There is also a stand on the long side, so it is also a point that you can stand smartly when not in use.
With a self-supporting stand
Space saving when not in use
The approximate body size is 220 mm long x 220 mm wide x 49 mm high. Heat resistant temperature 120 degrees. Please check carefully before purchasing as it may not be stable depending on the shape and size of the sink. The price is, of course, 100 yen (excluding tax).
