Pickle food is loved by people all over the world for its special taste. What makes it different is the changeable taste owing to the preservation of time. So it can bring people different tastes and experiences. This is a pickle box which can detect different tastes. This kind of box can detect different acidity of pickle and show it by using pH paper which makes it easy to select the favorite flavor. It’s not only useful but also beautiful, with the acidity going up, the test paper on the lid of the box looks just like a blooming flower gradually turning redder. It can give people a delighted mood when people select the taste.
