Three sizes: 7 cm 12 cm 18 cm
Grain sieve is identical for all three sizes. One might expect that the grain is gradual for the three strainers, but that is not the case. They are manufactured on the same model: a sieve caught in a steel rim with a welded handle easy to handle and a small steel rim to guarantee a good support on the pan. The downside for small strainer that fits on any of my cookware. This is not really a problem as it may be intended for use in hand.
The quality is good, the regular screen and easy to clean.
