The Silver Swirls box from Crayola is my favorite box ever! The Silver Swirl line started in 1990. I think it was a failed attempt at a glitter crayon. That is what I got from reading the patent. I bought these crayons when I was really young and used them all the time. I loved how shiny and smooth they were on the paper. There was nothing else like it and there has not been anything like it since. Like I said these are my absolute favorite. I really wish Crayola would bring these back.
I think I have figured out why they were sadly taken out of the market. In the patent it mentions a "metal-swirl version of a Crayola® crayon which contains fine particles of aluminum; however, while this type of crayon yields a swirl effect and alters the typical pigment, such a crayon does not impart a glitter effect to a substrate." Were silver swirls the first attempt at glitter crayons? Were they were taken off the market because they contain aluminum?
