This 1 fl oz bottle of Residual Oil Remover (ROR) Lens Cleaner comes with a screw off cap and a dropper tip. This bottle is excellent for smaller lenses such as viewfinders, eyepieces, microscope objectives or any other surface where you don't need to cover a large area with a mist. (For larger lenses the 2 fl oz bottle comes with a spray nozzle). Use ROR with a high quality lens cloth for the best results.
