I also own one of the PlePle Choco Wrap Pencil Cases, but I can't really recommend it. It's a beautiful little case, but it's difficult to put a pencil sharpener in there. And once your pencils have been sharpened down to half height, they no longer stick out of the pockets making them hard to pull out. It probably works really well for pens however.
The Transformer almost has this problem, but since it opens up and is generally a wider case, you can look right in there and pull out what you need. Plus, it holds a sharpener nicely.
