Cubics book cover round zip (paperback size)

When I go out, I carry a book in the front pocket of my backpack. There are many other things in my pocket, so the book bends and gets dirty every time I put it in and out. A new book, which was comfortable with the paper spicy, quickly became ragged.

If you stick it in the backpack as it is, it will be damaged immediately.

The lineup of book covers handled by Amazon was checked with the urgency of "I feel sorry for the book if I continue to do this." I bought a product called "Cubics Book Cover Round Zip (paperback size) " that had a lot of customer reviews.

A book cover with zippers on 3 sides. If you set the paperback book inside and then close it all the way, it will protect you from bending and dirt. The material is nylon, polyester, etc., and if it gets a little dirty, it can be wiped off quickly with a wet cloth. There is also a bookmark of ribbon material inside.

The size of the cover is about 1 cm x 12.5 cm x 18.5 cm, and it supports up to about 600 pages thick paperback books. When I put in about 600 pages of "The Magic Mountain" (Thomas Mann), it closed smoothly without feeling any strain on the zipper. I also tried to put in a new book, but this is NG only for paperback books. However, the "Kindle Paperwhite" I have fits in just the right size. Although it is not the original purpose, it can also be used as a case for thin electronic devices and small items.
