Every once in a while a design emerges that sets the new standard for an everyday product. The toilet paper dispenser is one of those products that has remained virtually unchanged for God knows how many years until now. The Eva Solo TP holder attaches to the wall on one end and uses what are probably spring loaded plastic tabs to keep the TP from spinning off. When finished, just simply slip off the empty roll and put on a new one.
