Pink Lady: Puffy Stickers (Japanese Idol, 70s)

Kawaaaaii!
These cute stickers are from a time, when the idea of the Japanese "idol" was only just starting to spread - and it all started with the two gals; The Pink Ladies! 
Own a little bit of sticker history, with these awesome stickers, and impress your bank or the tax system when you need to send them a letter.

Condition: Good! New and unopened. Not sure if the design has faded over the years, or if it's sun-damage - probably the first.
