Instruction:
I'm planning a month-long trip and am wondering which of these items are okay to be kept in a carry-on bag. Could you help classify these items as "allowed" or "not allowed" by the TSA? Toothbrush, Cologne, Beard Shaver, Alcohol, and Bottle Opener.

Response:
Here is what's allowed and what's not allowed in your carry-on luggage:
- Allowed: Toothbrush, Cologne (3.4 Ounces), Beard Shaver
- Not allowed: Alcohol, Bottle Opener
