The object i received is a pack of sticky note. It is yellow, and with 3″X3″ size. It is a perfect square, and the whole pack of sticky note seems around 100 pages.

The usage of a sticky note is to remind people to do them. Some people put them on lap-top, some people stick it on the side of the desk.

The sticky note that i searched on google are mainly yellow, but there are few that is in different color. I believe yellow represent a warning, which helps to remind.

The website of the brand of this sticky note is Post-it. In the website, it is easy to access to the sticky note and some other similar product.

The picture shows that the sticky note has also been made as an app in computer. When people open up the computer, the sticky note pop-up and remind people the job they didn’t do or staff they need to finish.
