Specifically designed to hold papers, photos, drawings, memos, brochures, business cards The Stas Paper Rail is designed to hold papers, photos, drawings, memos, small catalogs and other light weight items. The paper rail works by gravity. Just insert your items from below the rail and push upwards and presto! Your items stay in place. To release your items just pull down and out they come. The rail works with a set of clear marbles that with gravity will gently hold on to the items placed inside. The Paper Rail can be used in offices for peer memos, reminders, calendar of events, or brochures. At home you can place them in the kitchen to hold recipes when cooking allowing for more counter space. Or in the kids rooms for holding mementos, photos, or homework assignments.
