Attack Tacks

Calling all manga geeks and Japanophiles: these Ninja Tacks will make your corkboard notes seem like they were posted with deadly accuracy... possibly by assault from some band of wandering, shuuriken-wielding ninjas. Who knew that posting your weekly supermarket list would ever seem so dangerous? Via Hello Bauldoff, at chromology. Get a bunch for $12 (I'm not sure if that's US or Canadian - go look).
