Butterfly Notes Series Evaluation of Butterfly Notes Series ***9 books, one for each subject, are the general review and explanation books for the college entrance examination produced by Butterfly College.
Size: 16, the same size as high school textbooks, and the thickness is generally about 2 cm.
Paper: 80g double-sided adhesive paper is used, which makes the paper smooth and feel good, and the yellow color of the paper protects the eyesight.
Face value: The face value of the whole book is the highest among the teaching AIDS of the college entrance examination at present, and it has a strong artistic sense. There is a gold-plated LOGO of Butterfly College in the upper right corner of the cover, which is atmospheric and anti-theft.
Printing: the text is printed in two colors, and the printed font is clear. There are green printed marks on the back of the books, and each book has plastic packaging. After opening the plastic package, there is no ink smell, and there is a faint book fragrance.
Typesetting: The typesetting of the whole book is very loose, the font is standard No.5, the line spacing layout is reasonable, and there is a blank writing sidebar on each page. The experience is very good, and it is convenient to take notes while reading.
Binding: I'd like to emphasize that all the books of Butterfly Notes are bound by thread lock, which can not only be easily opened at 180 degrees, but also prevent the pages from falling off. It seems that the cost of this book is really not low, and the cost of sewing is at least twice that of ordinary binding.
Pricing: Butterfly Notes series books are reasonably priced. For example, the math of butterfly notes is 2 1 print run, and the price is 59.8 yuan. On average, a print is less than 3 yuan, mainly because it is as thick as a book (80g paper), and the cost is already high. Teaching AIDS in the market are generally priced according to an Indian 4 yuan. According to this logic, the pricing of this book is very low-key.
