We are trying to find a manufacturer for a 6 hole punch that would potentially fit in the binder. Until then, something like this: https://www.amazon.com/Rapesco-Adjustable-Six-hole-Organizers-PF66P0B1/dp/B000J6EXM6/ would work well. Another company currently makes a binder version but it is quite expensive with poor reviews: https://www.amazon.com/Filofax-Portable-Hole-Punch-B340119/dp/B000SHUGWC/
