Finally, it is time to explain the design a bit.
Inspired by Stantang, why don't I make the whole luggage crystal?
So now I have use the transparent material. Simular to Philippe Starck Ghost chair, but I think the plastic material is thinner and more elastic.
The wheel can be adjust to the back of the luggage so they can slide horizontally or vertically. Handle is simple to match the curve design. I have to take the real crystal away, as they really make the design old fashion, I think this will look more modern than before design.
