I possess the dogs bollocks of all filofax's (in my opinion). It's an A5 Metropol Zip in black and stores everything I need to organise my life. It's big and bulky (it's a bit like me, really) but that suits me down to the ground because I have everything I need in one place - and a big zip to stop it all falling out. It also fits perfectly in my "work bag".
My life, my love... where would I be without it? Lost and confused most probably!!
