This is the strangest site. I have never bought from here so I cannot vouch for their service. But they sell cheap generic paper for Filofaxes as well as replacement ring mechanisms for Mulberry and Filofax binders. Not sure how they work or how easy the rings are to replace but if you do have a beloved binder which urgently needs new rings, it would be worth giving this a shot.
Yes they are Krause – which almost never go wrong, luckily!
I thought Mulberry rings were Krause ones. I wouldn’t dare change the rings on my MB and their brilliant customer service do it so well and for such little money or even for free.
