The "Heavyweight Definitive! 16 Works of Schoolgirls 38 Hours" is a grab-bag-like set product, but its high volume gives it a good cosmetic value. It is also very practical, and I personally found the works by Mirei Morishita and Misuzu Kawana to be especially great. I was wondering which work to pull out every day, and it has become a definite heavy favorite.
