My Ebonite Bulkfiller loses its shine over time, how can I solve this?

It is true that the colour of the Ebonite material can change when it is exposed to continuous light, therefore we recommend our customers to put the pen in its box or pen case after use.

Like all types of hard rubber, Ebonite is also subject to a gradual oxidation, which is inherent to the material.

This has nothing to do with the general quality of the material, since we exclusively use Ebonite of supreme quality, manufactured by SEM in Hamburg, Germany.

If your pen experiences any kind of deficiency or discoloration of the housing, please contact us via the contact form.
