Clip Sticker special safe food in the frigde

Hi folks,
This is a tool to avoid waste food in the doubt of "when it has been opened?!";
I mean this is a good thing to remember when you've open coconut milk, tomato juice or whatever needs to be kept only 3-10 days in the fridge.

Just add a piece of paper in the box, write opening date of the content, and close it with the other part! done.

This has been done thanks to a first work done by Quin.
You can find enclosed my fusion 360 file too.
