Clear Reminder: Bright yellow background with bold black text helps make the baby on board message easier to notice during daily driving, parking, and routine road use. 2PCS Set: Includes 2 matching signs, convenient for using on two vehicles or keeping one as a spare for replacement when needed. Rear Window Use: Suitable for rear window or rear side window display on clean smooth car glass, helping present a clear sign without taking up much space. Easy Apply: Peel off the backing, place the sticker on the glass, and smooth out bubbles for a neater finish, with simple removal when replacement is needed. Before Purchase: Please confirm the sign size, installation position, and glass surface condition before use, and place it where it does not affect driver visibility.
