ringpärm

Ringpärm is a Swedish term referring to a binder, specifically a type of loose-leaf binder that uses metal rings to hold punched paper. These rings are typically arranged in a D-shape or O-shape and open when a lever or mechanism is activated, allowing pages to be inserted or removed. Ringpärms are commonly used for organizing documents, schoolwork, and office supplies. They come in various sizes, with common ring diameters including 25mm, 30mm, and 50mm, which determine the capacity of the binder. The covers can be made from materials such as cardboard, plastic, or faux leather, and may feature additional pockets for storing loose items. The punched holes in the paper are standardized, usually in a three-hole or four-hole pattern, to ensure compatibility with the ring mechanism. Ringpärms are a popular organizational tool due to their flexibility and ease of use in sorting and rearranging documents.
