This is an announcement for the paper "Zippin's embedding theorem and amalgamations of classes of Banach" by Ondrej Kurka. Abstract: It was proved by Dodos and Ferenczi that the classes of Banach spaces with a separable dual and of separable reflexive Banach spaces are strongly bounded. In this note, we provide an isometric version of this result.
