A bookend that is indispensable for organizing bookshelves. However, if you pull out a few books, the remaining books will lean back and the bookend may fall down.
I found a nice idea bookend that solves such a problem with Daiso. Its name is "Bookend with stopper that does not shift". Available in black and white.
The mechanism is simple. The folded part of the bookend (the part on which the book is placed) has a jagged waveform, and the width of the partition can be fixed by engaging it with another bookend. In other words, two identical products are required to achieve "no deviation".
Since the stoppers are firmly engaged with each other, even if a heavy book leans against it, it will never slip or fall over. It is safe to take out several books.
Even if a heavy book leans on it, it won't fall over!
The partition width that can be changed depending on the part to be engaged is about 15 cm at the minimum and 26 cm at the maximum.
Be careful when using it on a flat surface. Since the stopper is thin, if the floor surface is uneven, it will not click and will shift.
If you are suffering from an avalanche on a bookshelf, why not use this bookend to solve it? A more comfortable reading life is waiting for you.
