Update: got an answer asking for a pair of orig. inserts to take these as pattern/template. The production will be possible if the amount of at least 30 pairs is reached. The price will be around 100,- EUR for a pair.
Question 1: could someone provide a pair of the orig. OEM inserts as pattern/templat for the production?
Question 2: what ist the demand of the inserts? Is it realistic to reach at least 30 pairs?
