Please help me translate

Hi, I'm building one of the VIP cars and was looking through the decals on the sheet that comes with the model. One of the decals included is written in all Japanese and I was wondering what it said. I found the K-Break website was selling stickers with that word. On the attachment it is the sticker to the far right sold in different colors. Can someone tell me what it says. Thank you in advanced.
