马上要用完的铅笔头，丢弃是不是很可惜呢？yankodesign介绍的这款充满想象力的铅笔套设计很环保的解决了这个问题：

Don’t Give Up The Stub

Unless you are one of those twisted minds that create art out of pencil stubs, the normal routine would be to discard them. But from now on, you can become a pencil stub collector. The 1 + 1 = 1 is no mathematical error, but applied to this equation: 1 pencil stub + 1 pencil stub = 1 long pencil. Really functional and awesome!

Designers: Hoyoung Lee, Youngwoo Park & Jinyoung Park
