The cover opens upwards for easy refilling. Inserting a roll into the dispenser is done by simply letting the paper drop freely, pulling it until the marked line, and closing the cover. The fully opening cutting mechanism is easily accessible and simple to clean. When paper is not visible, there is an easy-to-use PUSH bar for paper feeding. Braille instructions are provided for visually impaired on the PUSH bar. Controlled consumption, minimum resistance to draw and high capacity: 420 - 800 sheets per roll depending on quality. The lock can be used with or without a key. The whole roll is always used. Almost fully used rolls automatically drop into the stub roll position when the roll has a diameter of approximately 7.5 cm. The empty cores can simply be pulled out side wards from the back of the dispenser and recycled. Main raw materials of major plastic parts and lock: ABS (Acrylonitrile butadiene styrene), PC (polycarbonate), POM (polyoxymethylene). Paper consumption is easy to control, thanks to the transparent side panels.
