A flip chart holder, also known as an EASEL, is a device used to hold large sheets of paper or poster boards in place for presentations. It typically consists of a tripod base with an adjustable frame that can be adjusted to different heights and angles. The frame is designed to hold the paper or poster board securely in place while allowing the presenter to easily move it around. It is a popular choice for classrooms, conference rooms, and other settings where presentations are given.
