This is an A4 clear holder/file with a design faithfully reproducing the sheet music of the Zen-On Piano Library. I have kept it carefully in my bookshelf at home, but I am selling it to organize my collection. It is unopened and has been stored in the original clear OPP bag. The bag has traces of stickers from when it was purchased, but the holder itself is like new, with no scratches. It is now discontinued and very rare. ―――――――――――――――― 【Product Name】 Zen-On Piano Library "Complete Translation Hanon Piano Textbook" Design A4 Clear Holder - Size: 31cm (height) x 22cm (width) 　It is made slightly larger in both height and width to accommodate A4 size (210 x 297mm). - Purchased from: Shimamura Music 【Product Description】 From the Zen-On Music Publishing Company, this is the "Zen-On Piano Library" sheet music, a standard textbook that anyone who has studied piano has seen at least once, published since the 1940s. It is made with thorough attention to detail in the quality of printing, paper, and design. This series is an authentic series that faithfully reproduces the cover design, colors, and fonts with the cooperation of Zen-On Music Publishing Company. --- For those with piano experience or music lovers, it is a piece that will evoke a sense of nostalgia from its texture and make you feel like you're standing up straight. Even those who are unfamiliar with the original sheet music will be able to enjoy the unique colors, sense of style, and world view as a general design item. For storing and carrying sheet music copies, lesson materials, school printouts, general documents, and booklets. Or for those looking for music-themed stationery or a slightly special clear holder, it is also recommended for collections. Because almost the entire surface is a unique blue color, it is practical because it is difficult to see through the documents inside and easy to find. This time, I am selling three types of items: Hanon and Czerny memo pads, staff paper notebooks, and A4 size clear holders, so please check them out if you are interested. Thank you for looking. - Title: Hanon: The Virtuoso Pianist - Publisher: zen-on piano library - Series Name: ZEN-ON Piano Library - Publisher: NAKANO CO., LTD.
