This is a miniature mascot of Stitch from Disney Easter. The size is approximately 3cm high for the face only, and approximately 4.5cm for the whole body (excluding the chain). When you shake it lightly, the arms and legs pop out. The body is stored inside the face, and when you shake it, the bottom of the face opens, and the stored arms and legs come out. When putting them away, you can store them by attaching the legs. It's fun, and you'll want to take them in and out again and again. I have never used it as a key holder, and I have been playing with taking the limbs out and putting them in.
