Universal SING Gunter Pinback button Approximately 3cm in diameter For SING fans (o^^o) My child kept this in a case as part of their collection. Since it has not been used as a pinback button, I have listed it as "near new". There are no noticeable scratches or stains, but please refrain from purchasing if you are looking for perfection. As it was managed by a child, there may be minor scratches or subtle scuffs. If you are concerned, please refrain from purchasing.
