I have the Amethyst, and I'm sitting here with it in my hand now, with both product pages open. When I use the "view actual size" feature, and hold the toy up to the screen, it matches the Bent Graduate almost perfectly, and fails to line up with its own image.
And yes, I'm using the "view actual size" feature correctly. My credit card lines up perfectly, and I've grabbed a few random toys to use as a control group, all of which line up perfectly, including other toys from SSA Glass.
The Amethyst has just as much of a pronounced hook shape as the Bent Graduate pictured on the website. And I'm definitely not complaining.
