# Retrobright to handle yellowed plastic

## Restoring yellowed-plastic

If you are buying a very old drawing tablet, the plastic may have shifted colors and turned more yellow over time.

Below are two Wacom GP-300E pens compared. Both come from the original Wacom Intuos Line released in 1998. The one on top has a typical look of the pen when it was released. The one on the bottom exhibits moderate yellowing.

This color change may be reversed or reduced through a process called **retrobright**.

The video below provides clear instructions on how to perform the retrobright process.
