What you're buying here are NOT finished pauldrons. You are buying a 3D print of the pauldron bases and the grotesque lions, which you will have to paint, glue and add a chain (not included!) to in order to make them wearable.
I have instructions on how to do that on my website
(down the page, under "The Pauldrons").
Also note that the two pauldron bases and the two grotesque lions are stacked on this 3D print file. In the rendered pictures and the 3D view of Shapeways it's difficult to see all four parts. Rest assured, what you will get is two pauldrons and two lions.
I also have the crown
, a fake embroidery 3D print
and a crown ring
for Cersei on Shapeways.
