How hard is it to find 2026-2030 A6 Techo Iyo Okumi set?

I recently got regular with journaling and immediately got hyperfixated on documenting my life from this year…I feel a loss for all the years I missed because I didn’t journal regularly. I’ve had a rough childhood so my memories are already spotty. I’m kicking myself for not doing it.

What do you guys think?

Edit - please give me links / recs for where I can find a cover on cover for the journal also, thank you!
