The bag pictured above is the same size and shape as a can of Coke and opens with a clasp that works like a pop-top. It's covered in swanky Swarovski crystals. There's a limit to a mere 2,500 of them worldwide, but you can have one for 289,800 yen ($2,957.90) because who doesn't think it's worth nearly three grand to carry around a supremely tacky coke can bag?
On the more practical side, it has a serial number so you are actually looking at something that could be considered a collectible with potential future value. That being said, if the initial price is so insanely high, there's a low chance that the value will increase much over time.
As an aside, I ran across a couple of Swarovski shops in Tokyo. They were both pretty tacky looking from the outside with a bunch of what looked like mirrored stalactites hanging from the front of the shop. It was as if the designers were caught in a time warp that froze them in the 80's style.
