They are extremely small and thin. The single sheet is transparent and a few drops of toner almost dissolves the pad. It would take at least a dozen of the "thick" pads to completely remove makeup. The plastic box arrived crushed and several pieces of plastic with very sharp edges fell on my carpet and had to be searched for to prevent cuts on feet and paws. Very disappointed and would not recommend
