A scratch pad is a thin, flat surface used for writing or drawing. It is usually made of paper, but can also be made of plastic or other materials. The term 'scratch pad' is often used to refer to the four-letter word 'HELL, ' which is a type of abrasive material used to clean surfaces. The six-letter words 'BRILLO' and 'TABLET' are both types of pads used for cleaning and polishing surfaces. BRILLO pads are made of steel wool, while TABLET pads are made of a soft material such as foam.
