There are three waterfall structures that when folded on score lines and adhered together create four cascading sheets with a strap and mat. Use the magnets to secure the mat to the top. The large waterfall measures 6.25″ x 8.25″ and the two small waterfalls measure 4″ x 6.25″. These waterfalls can be used in a horizontal or vertical layout. Use with extreme care. Neodymium magnets are strong, brittle magnets that need to be handled with care to avoid injury. Keep away from children, adult use only. Strong magnets may be harmful to pacemakers. Imported
