Example Output: negative

Example Input: This did not come as a ball.. it came already fluffed as if someone had already played with it. Probably is a knock off as others are suggesting. Awful packaging, the box was all torn apart. Also took forever to get here. did not receive it by Christmas as the seller indicated. Please don't waste your money on this scam

negative
