Because of the white background color of the Amazon page, I thought the medium and larger stars were just the outer ring. It makes sense that they have a white center, so you can use them to put names on. There is no sticky backing, you will need to tape them up. The name of the stars is misleading. There is no sparkle on these stars, No glitter, no reflection except on the gold portion of the stars. The stars I received had different colors on the stars than pictured here. The mid sized stars were "rainbow" the larger ones were a darker blue. The back is completely white, so you could have a project where the students fill in the back of the star themselves.

Really, there is nothing particularly great about these stars. The cut edges are good, the gold is shiney...You could use them for nametags etc - but for "sparkle" look elsewhere.
