Only the very top is iridescent. The accordion and the base are both cloudy clear. It doesn't look like it does in the picture, and I probably would have just gotten the cheaper clear glitter if I had seen it in person.
I was really excited to get this in the mail, it finally arrived today, the second I opened it I noticed that my popsocket looked nothing like the one in the pictures. Mine isn't nearly as full as the one in the pictures. The one I received has about half of what the one shown on the website has.
I've been buying pop sockets to showcase my fandoms and switching them out every now and then, but for some reason this time when I bought a couple of the Pokemon ones, the print on it was low quality / looked bad. The design is super cute, but was bummed that the image quality was not the same as others I've gotten from the website. Will still use it though!
