Caution - spacer sleeve Transparent plastic 12 mm length - just a piece

Why do we provide as many Diztanshülsen and sent only one and this one pays 4.70 eu shipping costs?
One would have to send a piece of this spacer sleeve with an envelope .. Without or at least less shipping.
Before ordering, we have so übelegt that should fit on others for our work. But only one piece?

I want to send the item back, because this is a bit too high. Why is there is a lot of different images of spacer sleeves and confused and the other? You buy what you see.

And I thought I paid the full price for all Diztanshülsen in the image .. Not for a piece
