Look at the picture, this is a set of WMF brand "GalaPlus" series soup pot set. Visually, it is a set of 7 pieces, including 16cm sauce pot (that is, single-handle milk pot), 16cm high/low soup pot, 20cm high/low soup pot, 24cm high soup pot and 20cm steamer.

You guessed it, soup pot, frying pan, pan, etc. These pots are mainly different in shape and material (but the structure of China wok, which is exclusively sold in Asian market, is different from that of soup pot). These pots you bought can be boiled and fried. Like you said, it depends on personal preference. If you fry something, you need to master the heat to achieve the effect of "physical non-stick". It is recommended to download videos online (videos of Zbignier and Fissler can also be used in a similar way).

"Cromargan" is the trademark name registered by WMF for 18/ 10 medical stainless steel. 18/ 10 is a common scientific name (that is, a steel alloy containing 18% chromium and 10% nickel).

"GalaPlus" is a mid-range series of WMF. It is obviously too expensive to buy it at the price of 500 euros in the country of origin of the brand. This price is more expensive than the seller's price plus profit.

I hope it helps you.
