I know this little useful tool from a Chinese blogger. Basically it is a three way lip and eyeliner pencil sharpener.
It has a little instruction paper teach you how to use it.
It is really small! Shorter than my pinky LOL.
The sharpener is tiny! But works perfectly for pencils.
Used as sharpener:
When your pencil eye-liner gets smaller, you can use this as a handle to hold it.
The third way, use it as a cap!
I love this little sharpener tool. It only cost $1 (I found it in store for $2).
Tiny, useful, valuable, cute, perfect for traveling or just everyday in your bag! It is super convenient.
