Far Infrared HandStrap: Mysteries of the Unknown

This exotic wrist strap claims to make use of bio-ceramics, a composite of lead-free minerals, to douse your arm with far infrared rays and help with blood circulation. Though "far infrared rays" might sound sinister if you're not familiar with them and their uses, they are supposedly quite healthy.

You can't see far infrared rays in the sun's light, but you can feel their warmth absorbed into your skin. In addition to their blood circulation benefits, these miracle beams are also said to naturally reduce inflammation, decrease pain, and revitalize skin cells. All that for only 780 yen (approximately $6.33)!
