Example Input: The brushes have good quality. They are soft, strong and easy to clean. It is good to have a lot of different brushes. As a beginner, I’m very happy with my purchase (I know they are all useful, I just need to learn how to use them all).
Example Output: positive

Example Input: These are postcard stamps that the seller takes forever (pun intended) to mail. It was amazing though ... Once I tried to cancel for taking too long they shipped that day. Soooo incredibly irritated with this purchase.
Example Output: negative

Example Input: The product did not affix to my phone properly, I tried twice with both in the box. I could not type on the phone well or open apps. It is a terrible product.
Example Output:
negative
