Jackets can be made from almost any material, which gives the necessary freedom and uniqueness. For example, a pencil case made from a meteorite is not unrealistic at this time, and there would certainly be someone who would want to own such a pencil. However, several blanks can be used for one good specimen, which is why the price for such a pencil is really high. As for the coats, it is mainly about the lack of certain materials at this time. For surface treatments, it is important to find a reliable partner so that the result corresponds exactly to your requirements. For example, in the case of anodizing, we only found it in Austria.
