Leaf Cord Ties: Functional Or Frivolous?

Keeping electronics’ power cords organized is really annoying, so we’ve gotten in the habit of wrapping them up with rubber-bands. The nice thing about rubber-bands is that they don’t cost much (especially if you steal them from work), but they aren’t very cute, and sometimes the rubber rots, causing them to snap out of nowhere. Lufdesign’s Leaf Ties do the same job as rubber-bands, but in a rather elegant, nature-inspired way. But is it silly to spend $7 (plus shipping) for 12 ties? [Lufdesign via Design Scene]
