The style (25 cm) is very short, just enough that way. A few more cm would be but still nice.
In appearance very nice, especially when compared with other brushes in the price category.
The glass liner is not rounded so that it corresponds to the brush form, but on the contrary, the outside (inside) lower than in the middle of the inside. This slight dirt in use can accumulate.
Recommendable All in all, when hard bristles are preferred, and the length of the style is not so important.
A replacement brush is whether you can re-order more, I have not yet figured out.
