Colorful Beans Earphones: Unfortunately the earphones aren't carried online, so we'll have to direct you to your nearest Daiso store to get these. For $1.50, these earphones are worth every penny. We like that they come in fun colors, have a longer cord than your standard Apple earphones, and fit very comfortably.
Wall Mounted CD Player: A former colleague had this CD player in his office, and I've often admired how its simple design would compliment the rest of the room. Muji's Wall Mounted CD Player is meant to be mounted on a wall with the cable hanging down. To play the CD or listen to FM radio, simply pull the cable. The volume and search controls are placed on top of the player, which also has speakers built into the body. It also comes with a remote control to play or stop the music so you don't have to be next to the cable to control it.
USB in a Bottle: How pretty is this USB stick? The idea of a USB in a bottle is clever, and along with storing your average 2 GBs, this USB is also a nice accessory to showcase on your desk. We love the packaging it comes in as well.
Pantone Phones: Design geeks are probably super envious of these Pantone phones by Softbank. They come in 8 Pantone colors, have a bunch of nifty wallpaper widgets, and are waterproof. The biggest buzz around these phones is that they can detect radiation.
Keyboard Memo Pad: Often I've been left Post-its from coworkers letting me know I got a phone call or email while away from my desk. Muji makes this more fun with these keyboard memo pads that indicate things like "call", "email", or "urgent" on the memo, and are designed so the memo can be folded and placed on a keyboard.
