This is a container of Sephora's "Glamglow Gravitymud" face helping product. Why is it Sonic branded? It was a give-away item at the San Diego Comic Con in 2016. For whatever reason, beauty-products company Sephora appeared at the comic con to raise brand awareness & was giving out these little product tins to fans. It's not the first time a Sonic cosmetic has been released, but it's a first for Sephora. Because it's a convention give-away item, it's likely to be limited & thus uncommon and collectible.
