The scientific use of color sticky notes

I believe you will be familiar with the post-it notes, just tear them off and paste them directly. In fact, there is no standard way to use sticky notes, as long as the sticky notes are used to achieve the desired effect. As a simple sticker, if we use it scientifically, it will be more convenient. Let's take a look together!

A) First select the location of the sticker, and then wipe off the dust or oil stains on the place to be pasted.

B) Hold the sticker first and show how to paste it properly

C) Because it is generally pasted on the glass, it is recommended to spray some water on the glass and the sticker when pasting, and then paste it, then adjust the position, and scrape the water with a scraper.

D) If there are bubbles after paste, use a needle to stick it, and then flatten it with a cloth.
