Initially I wanted a calendar a little smaller as the HEPTA 24 Quo Vadis, but I got caught too late: the format was not online or in specialty stores that I frequented. So I folded on the A4. All in all, it pleases me because my docs A4 are well protected inside ... Yes, I regularly transports documents in my diary and I like that they remain in good condition! Moreover, no complaints for quality, is the price! a little high though !!
