The Faber Castell Polychromos colored pencils work best on a smooth, heavyweight paper with a good tooth that can hold multiple layers of color. A paper with a weight of 100lb or higher is recommended to prevent warping or buckling. Additionally, a paper with a light texture, such as hot-pressed watercolor paper or Bristol board, is ideal for achieving the best results with the Polychromos pencils. **

The Faber Castell Polychromos colored pencils are high-quality and have a strong lead, so it is best to use a sharpener specifically designed for colored pencils. A good option would be the Faber Castell Grip 2001 sharpener, which is designed to handle the delicate lead of colored pencils without breaking or damaging them. Another suitable option would be any sharpener with a high-quality blade and a gentle sharpening mechanism to prevent the lead from breaking. **

The main problem with the Faber Castell pencil is that it tends to break easily. This can be frustrating for users, especially when trying to sharpen the pencil or during use. The breakage can lead to wastage of the pencil and may require frequent sharpening, which can be inconvenient. Additionally, the breakage can affect the quality of the pencil's writing or drawing performance. **
