The bowl and colander have a difference in height, so ingredients that tend to float on water are less likely to spill out even when placed under running water.

[The Flat Edge Deep Bowl series is available in three sizes: 15cm, 18cm, and 21cm]

Hygienic and easy to use flat edge

Koinu brand bowls and strainers have flat edges. Usually, the edges of bowls and strainers are rolled up, but by making them flat, they are less likely to collect dirt or water, and can be used hygienically for a long time. Making them flat also makes the edges wider, which has the advantage of making them easier to hold firmly with one hand. It is also useful when you want to hold down meringues firmly or when transferring vegetables from a bowl to a strainer.

Sharp spout

Another benefit of the flat edge is that the spout is easy to pour. You can pour liquid exactly where you want it, which makes cooking go more smoothly. It's also great that it's easy to pour highly viscous liquids like eggs.

A beautiful interior

The inside of the Koinu Brand bowl appears to be beautifully shiny. This is because it is finished with electrolytic polishing after matte polishing. When whipping cream, the whipper and bowl rub against each other, and tiny amounts of stainless steel can come off, causing the cream to discolor. However, by smoothing the surface with electrolytic polishing, this discoloration is less likely to occur. Thanks to this commitment, which spares no effort, you can whip pure white cream and meringues with peace of mind.

Long-lasting, durable wire

Colanders tend to be fragile and need to be replaced frequently, as the mesh can tear or become misshapen. Koinu Brand's colander uses a thicker wire of 0.57mm, making it less likely to tear or lose its shape, so you can use it for a long time. Its incredible strength and durability means it won't collapse even when carrying a weight of over 8kg, making it a professional product.
[The base has legs, so it can be placed directly on the sink for hygienic use.]

The perfect size for more use

The size is 18cm, which is close to that of a regular bowl, so it is naturally useful for everyday cooking. It is the perfect size for any purpose, such as putting cut vegetables in for curry, draining boiled soba noodles, or preparing fried chicken.

This 3-piece set can also be used like this

The bowl and colander are designed to be at different heights, so even if you put ingredients that tend to float under running water, they won't spill out. Another point is that you can easily lift them up by inserting your fingers. The flat tray can be used as a lid to prevent ingredients from spilling out when draining them in a bowl or colander. It can also be used as a water catcher or a tray to temporarily place ingredients on. This 3-piece set will make your time in the kitchen a little more fun and a little smoother.
