What is the difference between Parkside X20 Team and Parkside X20Team Limited Edition

I’m trying to find out what is the difference between the regular Parkside X20 Team tools and the so called "Limited Edition". I looked at the specs of several tools and didn’t find any difference apart of the color scheme. The regular ones are green & black while the limited edition is trimmed in light-green & grey. The other difference is that the "limited edition" is 2-3 euros more expensive.

Any clues?

Thanks and regards,
