We've seen other "message fans" but they all are limited to a few boring preset messages. This fan lets you express your true self, with up to four LED messages you can program and store! Includes many symbols and special characters too! Each message can be up to 18 characters long, and the fan will display the message in different cool patterns (our image only shows one of the many patterns). Super easy to program with just some finger taps. Soft, flexible propeller blades make this safer around children or drunk partiers. The fan comes with a convenient carrying lanyard. Uses 3 replaceable AA batteries (included). The plastic body of the fan comes in assorted solid colors. The fan's body is about 3.75" height and at its widest point, is 2.25" wide.
