These are the medium-sized Zelfs, about 3" tall (7.5cm) to the tops of their heads, not counting the hair. They're made by an Australian company called Moose Toys. They have both a larger and a smaller version. The tiny ones don't have the detail and articulation of the other sizes, and I didn't find them quite as appealing.
The bodies are made of a type of semi-soft vinyl that is slightly squishy to the touch. You can press their bellies in slightly. The wings are an even softer vinyl/plastic. They have a nice feel to them and don't feel cheap.
These two now have an honored spot right on top of my computer monitor.
As always, you can click on the pictures to make them bigger. :)
