Weird, it says:Colours change because RGB and CMYK have different palettes.
If you use the "Eyedropped Tool" (key: "I") on a colour and then you open the Color Picker (coloured square of the Foreground Color) you'll see if a colour will be printed or not.
If you open the advanced option ("Advaced" button in the "Convert to profile" window) you can set a custom CMYK and load it for all images.
Look at my image
Triangle: the colour will not printed
Cube: the color will not shown on the web

Packing Details: "200 pieces per box"

Well, I guess you're right then.
