The mark consists of the stylized letters "EIR" displayed in bold, uppercase letters, enclosed within a rounded rectangle (stadium-shaped) border. The interior of the rounded rectangle border contains multiple concentric outlines that follow and repeat the shape of the outer border, creating a series of progressively smaller inset rounded rectangles that produce a layered, repeating frame effect. The letters "E," "I," and "R" are rendered in a bold, block style and are themselves outlined with concentric inner lines that mirror the letterform contours, giving each letter a multi-stroke, inset appearance consistent with the surrounding border treatment.
