What is one piece telegrams?

One Piece telegrams are a messaging system found in the anime and manga series "One Piece." They are used by characters to send urgent messages or requests for assistance to other characters who are located far away. The telegrams typically appear as small paper slips with text written in bold letters. They are sent via carrier birds or through other means of long-distance communication. One notable example of a One Piece telegram is the message sent by Luffy to Nami during the Enies Lobby arc, which helped the Straw Hat crew locate and rescue their captured comrades.
