Question about large LV agenda refills

[TIFFINEE]

I know that some of the Sanrio refills will fit in an LV. Has anyone come accross any that will fit in the large size agenda? The filofax refillsI bought aren't colorful and rather boring/plain. Thanks for any advice.

I've used the sanrio ones for my PM last year, and also a lot of korean refills (lovely white, pucca...etc) will fit too..... I dunno about filofax....never used them before
