First, please watch the video.

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

Puppy brand bowls and colanders 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 has the advantage of making the edges wider, 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. Another plus is 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 are fragile and the mesh can tear or become misshapen, requiring frequent replacements. Koinu brand colanders use a thicker wire (0.57mm) than average, making them less likely to tear or lose their shape, allowing you to use them 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.]

Large size that can fit anything

It's a large size that can hold a lot of vegetables cut for a party salad, as well as plenty of boiled pasta and udon. If you use it with a mesh bowl made of woven wire, it can also be used as a rice washing bowl with good drainage. It is also recommended for kitchens with large families, as it can drain water and boil water at once.

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.
