This package Ã¥ÃŠof High Quality Aluminum Foil contains 50 sheets of pre-cut "hookah friendly" aluminum foil squares. These pre-cut hookah foil sheets use a thinner foil than standard household foil allowing a better distribution of the heat. Simply cover the top of your hookah bowl with these (shiny side down!) and poke a bunch of tiny holes with a toothpick or thumbtack and you're ready to go. These hookah foils are convenient, they cut down on set up time, and are perfect for traveling with. Each square measures 4"x4" and will fit any hookah bowl out there.
