These kawaii notebooks of Kiiroitori san are simply a must have if you love anything Rilakkuma/Kiiroitori; different that the other product I bought ( see: Rilakkuma Korilakkuma to Atarashii Otomodachi B6 Spiral Notebooks) these have CARDBOARD covers, so they're like small hardcover, spiral notebooks with beautiful covers. I adore them, so happy I made this purchase. (Bought both of them, worth it).
