Exactly as expected.
I have another Yarka St. Petersburg set- the Sequel set of 24.  This case is just like that one.  It does not hold generic full pans, they are slightly different dimensions to the Nevskaya Palitra manufactured paints. They do fit generic half pans and could potentially hold about 72 of those.  My sonnet, white nights, yarka full pans all fit into this pallette though.  I like the big detachable 9 well mixing flap.  The only difference between this and the tray that came with my yarka set is that came with lables on it of the colors and barcodes, etc.  Otherwise it's identical.  Holds 36 yarka type full pans.
