It's the Cancer Awareness Light-Up Pen.

The fine print says:

A portion of your purchase will be made to various cancer support programs throughout the united states whose mission is to provide the ongoing research and education it takes to find a cure. Thanks for your support!

And thanks for your spurious failure to capitalize "United States." It helps us not trust you. I don't know what you think you're saying you're going to do with "a portion of [my] purchase," but I'm here to say that if I buy that awful pink fuzzball, I will be taking my entire purchase with me.

"Early Detection Saves Lives" and "Lights As You Write" — nice capitalization. Too bad it doesn't light up when you have breast cancer.
