Designers, parents and anyone with a creative mind will love this Bottle Cap Sharpener. It's a simple contraption, a sharpener fixed into a bottle cap so that it screws on top of an empty bottle. Sharpen your pencils and collect the shavings. Great way to reuse a plastic bottle. Designers and creative minds will love for the artistic value this raw material will create. I can already picture myself using colorful shavings for my little girl's next art project. Designer: Yuchen Liu
