In fact, only the colour is different. The problem is the different availability, but above all the different market price. For example, certain colours are offered more cheaply by many suppliers, while others are difficult to obtain and are only offered at higher prices by some.
How do these huge price differences come about? The cheapest costs 364 and the most expensive 989. If you compare the products, it's always the same. If there is a difference, it is not listed.

And even if the one product is not currently available, there are others in the selection that look very much the same and make a nice price jump. -I'm confused.
