Silly but Elaborate

It's still busy... Sadly, my only pleasure is looking around some websites in a short break.
NIPPON STYLE is the project which commercializes ideas collected from the people. Although all of its products are quite silly, they have taken lots of time and energy to create.
(The following linked pages are written in Japanese. I hope you enjoy the images in them)

World's Smallest Die
The length of one side of this die made from brass is only 0.3mm (300micron). This is an example of wasteful using high-precision processing technology of Japan. This image shows that its size is about the same as a space of two fingerprint lines.
99,750yen (969USD)

This company also made "The Fastest Die in the World". It was named like this because of having been made from the same elaborate technology as an engine of Formula-One. The central point and the center of gravity of this cube are almost the same with 99.99999999% of accuracy.
49,875yen (484USD)

Wooden Keyboard
Each key and the cover of this keyboard are made from wood. It was made manually, and is more expensive than my PC itself. We have to take care not to bring coffee close to it.
262,500yen (2,550USD)

Condom Glass
This glass is originally a mold for manufacturing a condom. Once you fill this glass with a drink, you cannot put the glass on a table until you drink up (see the bottom shape of the glass). This page says that the smaller one is the Japanese specification and larger one is the European specification (especially French). What's the hell!
European Spec: 14,100yen (137USD) / Japanese Spec: 12,600yes (123USD)

Wrist Watch for Safe Sex
You can hide your condom into this wrist watch for an unexpected chance of sex. This animation shows how it works. This wrist watch will start to be made actually if the total orders come up to 120, but there are still only 8 orders. I think it's because of its bad design.
16,800yen (163USD)

Unfortunately, they are all too expensive for me (perhaps for many other people, too). If these were more cheap and sold on TV shopping channels, many people would buy them.
