Discbound Rings

Discbound / Mushroom Hole Notebook System

This was made to work with discbound or mushroom hole punched paper, such as the Happy Planner, Arc, Tul, or Jane’s Agenda planners. It allows for easy customization for a notebook. This is just the disc, other discbound accessories are linked below

There are profiles for each size. All include a single disc, four disc, and nine disc print set with brims and a set without brims. The ones without brims are made for plate with good adhesion such as cold plates that don't require them. I have test printed all of mine on a cold plate and have had no adhesion issues. The plates with brims is for plates with less adhesion to ensure they stick to the plate. The larger ones all have supports to help with the bridging.
