Junior Enterprises launches the SipGrip coffee handle for paper cups. It looks like one of those, 'why haven't I thought about this and make millions' ideas.

The SipGrip, which costs $6.95, is constructed of woven elastic, with a thick plastic handle that fits most disposable cups.
I get the point of this simple product, lots of cups are just too thin and are hot as hell. Only issue I see is to not forget to carry the SipGrip with me, when walking into Starbucks.
The SipGrip is sold online.
 They seriously need to work on their web site though.

Ideally Starbucks or any other chain picks this coffee cup accessory up and sells it for a couple bucks branded in their stores.
