Hey business people! Do you have business cards? Do you? Priced at ¥2,900 (US$31), there's this from Japan's Banpresto.
The aluminium card case has two compartments: one is for your business cards, and the other is business cards you receive during your meeting. The case is scheduled to drop this October and comes in two versions. One has a mock "mic" modeled after the old Famicom controllers. Feel free to scream in it when you get totally pissed off.
