Overengineered mechanical pencils

This video describes and pitches "overengineered" mechanical pencils from Japan, a perfect monday start for anyone who appreciates consumer engineering.

Note that it's an ad from a shop selling the pencils. I like how the voiceover artist reads the hyperenthusiastic copy with the most dryly corporate delivery. It's about halfway from "warehouse safety training video" to "Patrick Bateman reviews mechanical pencils". Great stuff!
