i have a pair of DS DMP XI. I have them stored in the box in a closet away from sunlight. i heard to prevent them from yellowing i should put them in a ziplock bag and try to remove as much air as possible. is this true?
i couple months ago i bought the DMP, deadstock. i havent worn them and probably wont for a while. What precautions should i take to make sure that the XI dontyellow?
