This is a single kbfx button based on kickme-plastic.png from pootie's "Kick me" button pack. There are three png's in the archive: normal, hover and pressed.
This button does best in its natural environment of 36 pixels. (pootie's original was 35 pixels, but I guess adding one line of dots can't hurt.)
I think a button without hover and pressed versions to go with it is a lonely button, no matter how beautiful it may be. So I GIMPed up such a pair to accompany pootie's original, because I think it is an exceptionally pretty orphan and deserves a good family.
