Just came across these things called Plings. Billed as clings for dinner plates, etc. I have to think these could be used for so much more. I am not a fan of their fall or Christmas graphics but these Halloween ones are pretty cute. If I was still working in an office building I totally would stick these on every one's coffee cup Halloween morning (except this year it's on a Sunday...). $8.95 for at least 24 clings.
