Product Description
I have always had a problem in reading. Because of the
work relationship, I have to read very heavy computer
technology books, and I need to look at the examples in the
book before the computer. It is necessary to press the book
with your elbows and look down at the computer screen
while looking down at the computer screen. This is
extremely inefficient. At this time, look at the bookshelf, it
is quite convenient to use.
