Stripper Glitter/Sparkles

[Sabretooth]

For the last few weeks I have been finding tiny specks of glitter on my hands, arms,clothes,desk,various paperwork and mouse pad. The specks are only visible in sunlight or lamp light. I just figured out the source ( not strippers this time ),
it comes off Christmas cards when the envelop is opened. I guess the " sparkles " loosen due to the mail handling process. From this point on I will leave cards unopened or open them over a sink. Very concerned about those tiny flakes getting into my eyes or food.
