Glitter Revenge is a unique service that will anonymously send glitter to your nemeses.

From the site:

“Nothing says “I’m thinking of you” better than a message of glitter. It also tends to linger and keep cropping up for weeks or months to come. We specialize in sending covert letters and packages to anyone you think needs one. Letters can be sent anonymously, or with a personal message. And of course, you don’t have to handle the scourge of the earth that is glitter. Check out our items for more information. ”
