I have always loved Sucess binders, though I have never owned one. I have used Sucess refills in the past though and they are fantastic. The ones I loved were miles better than the Filofax Time Management ones and were in bright blue and cream which was such a breath of fresh air compared to black and white or brown and cream.
Each one has a name but if you are interested in any of them, just show Joost Appelboom (he is in many Facebook groups and also contactable via the Appelboom site) my blog post and he will be able to point you in the right direction.
I have bought from Appelboom before and their service and packaging is lovely.
I have so many favourites from the ones below I cannot pick one! And usually I gravitate directly towards one I love. Which is your favourite?
