Tail box the same?

[Bhujang]

So while surfing through FastLad I noticed that the RedBull has a tail box that looks identical to the 130X difference being the RB one is only 99p! Are they the same or is there a major difference?

130X... BLH3725 Tail Case Set

RB... BLH3818 Red Bull 130X Tail Case Set

Why such the big difference in price?

The pictures do look different. The size of the box section of the red bull looks shorter, but that might be due to the way the picture is took.

Even so, why such price difference??
