The items concerned are referred to as “Justick Electro Adhesion Products”. This product group consists of various electrostatic display boards. These display boards incorporate electrical components that generate an electrostatic charge throughout the surface of the board. This electrostatic charge is a non-magnetic and non-invasive force that attracts flat objects such as paper, plastic and laminates towards itself. The boards are used to hold and display various types of papers, documents, business cards, pictures, DVDs, etc. They hold and display these items without the need for adhesive products, magnets or push pins. The electrostatic charge does all the holding. Each product operates using 4 AA batteries or a 6 V AC adaptor. Three representative samples were submitted and will be the subject of this ruling.
