It's outer diameter is 2cm, inner diameter 1cm. I don't know the material but the seller said it will work up to 500 kHz.
Will such one do the job? It seems too small to me...

If you don't know the material, there's not much to do except to experiment. When the seller said that, my guess is it might be N27, which is not so good (but I could be wrong of course).

At least the dimensions sound like they are about ok.

If you have an inductance meter (e.g. LCR multimeter) you can check if you can get the winding inductance (pri or any sec, all windings open) into the proper direction, i.e. in the order of 200 microHenry or more. Otherwise it's just wind and test with a gate driver and connected mosfet.

The others already posted good help and info.
In addition there's this page which is a bit outdated already, but still:
