The Problem

There are beverages available in the fridge. ¥5 for soft drinks, ¥10 for beers. But Premium beers are ¥20 per bottle. People are not aware of the difference.

The Solution

A reminder device is created to let the premium beers stand out! When the door is open, a buzz sound alerts and led blinks. Buyers will notice the ¥20 sign!
