Visible Freshness / tape

Visible Freshness
Visible Freshness

Visible Freshness is a tearable adhesive tape which is designed to make people easier to“see” how long the fruits or vegetables they have kept. We often put the fruit into bags, and thus are likely to forget the date when we bought them. Nor do we know whether they are still fresh.
Tear some tape and cling it onto the places you need, such as the fruit bag. When we tear away the double-sided-tape-like tissue, the color of the tape surface will turn darker as time goes by, which will tell the freshness of the fruit efficiently. When the tape turns almost black, it means that the fruit has been stored for too long.
