I sell pen wax and also the new Museum Wax.
The pen wax is a mixture of mainly carnauba wax with some other additives that enhance the gloss of the polished surface. It is quite safe and gives great results.
The new Museum wax is a neutral wax with no chemical gloss enhancers. All the components are natural and it is mild and absolute safe on all materials. I recommend it for hard rubber pens.
