stear / universal coffee mix

Many people use a harmful disposable coffee cover to stir coffee. I focused this behavior of human.

'coffee mix+ stick', when a user tears this coffee cover, it has a slim straw with gradations. A Simple solution makes users drink coffee conviniently.

And using "paper", it could be collected and recycled despite of a lot of garbage from stick.
Also, it shows some gradations on papered stick. It informs ideal ratio of water when user pours water into a paper cup.

Therefore, I cosidered all actions from stiring to drinking through a straw when people use a disposable coffee mix .
