Used stamps exchanges.

Why this? Picture is not meaningful.

Are these stamps stuck together?

The letter was stamped 22-5. Sealed in plastic, the letters were wet, and the stamps were moldy. I had to throw everything away. All thecstampsxwerexstuck together

I understand. But this is obviously not the sender's fault, but the post office's. There's nothing more you can do than wrap the shipment in plastic.

I understand that this is not a fault of the sender. The few stamps I saw looked nicely. (Belgium, Sri Lanka = my wish list)

I'm sorry that you received the letter in that condition. I have updated the rating from 1 to 4. It seems that the sender followed the rules and there were also stamps that you would have liked. It's not the sender's fault.
