Eco Factor: Record sleeve doubles as a human-powered record player.
Audio engineering company GGRP Sound has unveiled a unique cardboard record sleeve, used mostly to protect the record for any damage, which here doubles as an environmentally friendly record player. The corrugated cardboard sleeve can be opened up and converted into a human-powered record player.
The player allows you to turn the record via a pencil with detailed instructions printed on the sleeve itself.
