I love my LV monogram PM agenda and have been using the same one since 2008, so it is a good investment for me. Back then, I purchased the limited edition from the special exhibition featuring Murakami and LV in LA Geffen Museum for $500 + tax.
Over the years, the ring binder is definitely becoming an issue. It can't hold the vast volume of inserts that I purchased from LV as years went by. Now I need to thin the inserts into the dairy only before inserting them into the agenda so that the ring binder will close properly. But I don't really need those extra note pages, phone book, foldout calendar, and map, etc. in the pack. The issue only comes up after about 10 years of continued use and I can bear with it.
Also, the price of the refillable inserts has been increasing, from about $26 about 11 years ago to $86 in year 2019, but the design is lovely and it comes with stickers, bookmarks, world map and time zones...
