Cornwell wrench set question w/pic

[1982fxr]

Is it just an optical illusion how it looks like the whole set has almost the same beam length on all sizes?

Here's a shot of 3 of my Cornwell long series wrenches,as you can see they do differ in size BUT even in the official catalogue they all appear to be the same length.

It is because the tray the wrenches are sitting in is angled, so it appears the wrenches are the same length.
