When talking of thumb drives, people immediately think of very small USB flash drives, but Green House is not most people.
Once you buy one of the Thumb Drives, you might stop being one of those people too.
You may also become someone very adept at pretending you cut your thumb while chopping vegetables.
Long story short, Green House's Thumb Drive
is called as such due to it being shaped like a human thumb, pink “skin” and everything.
Looks are all that the product has to offer though. The capacity of up to 4 GB isn't that great, and the USB 2.0 connection is slow by today's standard (a tenth of USB 3.0).
That said, the price of the flash drive is 1,980 JPY (US $25.8 / 20.59 Euro). Not sure if chewing the nail on it voids the warranty.
