The larger the family, the faster the refrigerator shelves are emptied - a proven fact. If you are a bachelor or just not a fan of cleaning up food in a home food store, there is a risk that some products will deteriorate before you are done with them. Especially for those who are not used to monitor the shelf life of products, designers Kim Min-Jung and Kim se-Han have developed the concept of Fresholling timer. in fact, this is a standard kitchen timer, but it considers time not as minutes, but days. It can be attached to a bag of milk or juice and set the shelf life of the product. As soon as it expires, the device will let you know about it with a sound signal.
