Colour editor guide:
The prices should be meant in pairs. The value in the drop-down menu (size) is the size according to the sides (1 piece for the right side, 1 piece for the left side).
The matt and bright options only apply to the UNMARKED colours. The MARKED colours will always be bright or silk gloss.
In case you wish to colour or order your sticker using less colours, choose the red X (blank, no colour) function in the product colour selection window.
