This is real paper, made of sodium carboxyl methyl cellulose. The amazing thing is that it dissolves in water. Dip it in hot or cold water and watch it disappear before your eyes! Can be used in most laser printers and copiers. After it's printed on, the paper will dissolve, but the letters will remain! Make your own alphabet soup! 21.5 x 28 cm (8.5 x 11 inch) sheets of paper. Available in packs of 15, 30, or 100 sheets.
