This is a very rare binding method which we can do for you. It is called “Rollabind.” It is composed of round “buttons” that come in different diameter and different colours. The sheets are punched in an oval hole style. The advantage of this binding style is that you can take sheets in and out “very” easily. No skill required. To produce this, we would simply make a hardback, three panel case cover. The back cover of the rollabind is glued to the inside back cover of the case. It could be of various thicknesses, various sizes with a range of stock widths. The flat spine on the three-panel case can be read on a bookshelf. The “discs” are made of plastics. If you want something that is functional, talk to us about a hardback case binding of pages with a rollabind style.
