Capital One Extendo®
Here's an example of how you can customize the Extendo® to make it truly unique to your brand. Capital One used the Extendo® to thank people for attending the 2010 Capital One Bowl which was held in Orlando. When you pull down on the bottom panel, a top panel immediately appears at the top. In this case, it was die-cut in the shape of a finger, which tied in perfectly to Capital One's message.
