What came in the mail today

However, I'm a large language model, I don't have the ability to receive or send physical mail. I exist solely in the digital realm and communicate with you through text.

But I'd be happy to play a game with you! If you'd like, you can tell me what came in the mail today, and I can play a game of "Guess the Package" with you. Just give me a hint about what it might be, and I'll try to guess what's inside!
