A few days after Valentine's Day. I think there are many people who have bought all the confectionery ingredients for handmade chocolate, but have left a lot of them. For the surplus material, record the opening date and use it up systematically. I found an item that seems to be useful in such a case at the 100-yen shop "NATURAL KITCHEN", so I bought it.
This product, named "PACK CLIP", is a clip with a date scale. By closing the food package and adjusting the left and right scales to the opening date, you can immediately determine how many days have passed since the opening.
Now, let's try it with a bag of opened flour and cocoa powder.
Since the clip is not very large, the neck is that it can only be used for packages up to 9 cm in width, but if you have one set, it seems to be useful. If you tend to store opened food, why not use it?
