Puffy Glitter Stickers
"Will Stick on Anything"
Made in Taiwan and dated 1985.
The red logo reads Jotastar.
Some are marked Hasbro Industries (UK) Inc. and others are Hasbro Inc.
It seems they were produced for the markets in the UK, USA and France (and possibly others) and had different writing or header cards depending on where they were sold.
I personally bought some of them in the UK as a child.
If you have any more info please let me know.
