Pretty clever, right? They range in price from six to eight bucks depending on their size, but since they're currently available from a Japanese site called Bundoki, you'll have to tiptoe through a crudely translated version to buy one. Or track down a place that already imports them to North America. [Bundoki via Spoon & Tamago]
