The product page states the following: "For books of 24.1 to 50.2 cm in length (width front and back + back width). The width of the bag is adjustable." Furthermore, it concerns the type BC93Q, according to specifications for books up to 24.8 cm high.
This information is partly incomplete, or at least carelessly worded or translated.

I ordered the product for some hardcover books of 24.6 to 24.7 cm high. After receiving the product, the covers appear to be too small for the books.
The size 24.8 is the outer size of the cover (which should actually be 24.765 cm, 9 3/4 inches), and what really fits books is a maximum of 24.13 cm (9 1/2 inches) high. I also had a few smaller books, so not a big disaster in that regard.

The strange thing is that the product page as mentioned above states that the product is suitable for books of 24.1 to 50.2 cm in length.
What afterwards after personal experience should be mentioned on the product page is the following:
Outer protective covers: 9 3/4 x 19 3/4 inches, which equals 24,765 x 50,165 cm.
Inner size of protective covers: 9 1/2 x 19 3/4 inches, which equals 24.13 x 50.165 cm.

Why it has been decided to round up at conversion sizes for a product that has to be 'around' somewhere is beyond me. For safety's sake, I would recommend finalizing these types of things down, or simply giving the specifications fully enough.

In summary: the maximum book height for this product is therefore not 24.8 cm but only 24.1 cm. The maximum recommended book width (front cover + back plus the back) is 50.1 cm instead of 50.2 cm but will cause problems less often.

Note BagsXL: we have now rounded the sizes down.
