the colors in the i love kawaii book is not as bright as the 100% cutie,the type of paper use to print on the 2 books are different,but i love kawaii book is smaller in size,same content,and has a hard cover, so depends on your need,do u want to carry it around with you? buy the i love kawaii book or u prefer bigger size 100%cutie book,colour brighter,page quality better..i personally recommend the 100% cutie^^.
