Coro Coro Sub?

It would cost an arm and a leg to ship…
From what I gather, they are like phonebooks so they would be extremely heavy…

I think of them as 3 volumes of Shonen Jump glued together…
Of course I could be wrong…
tokirocket (Sp?) from youtube has a guide to learning japanese and in one video, mentions something similar and shows it…
It is big so $10 + shipping
