Japanese designer invents paper LED flashlight

The Japanese designer kazuhiro yamanaka Yamamoto has designed a minimalist flashlight. The material is just a piece of paper and a LED light battery. After the paper is rolled up, it is a flashlight that provides sufficient illumination.

When the user rotates the paper into a cylindrical shape, the intersecting slits are squeezed inward, and the LED lamps are automatically powered by two hidden switches. When the paper is spread out, the light is automatically turned off.
