Dr. Martens 1460 Pascal Mono White Boots

1460 Pascal Mono in Optical White UK7 US women’s 9 EU41 Worn once indoors for couple hours, excellent condition. Slight discolouration on the inside of the laces where they touch the metal part of the eyelet. I’m assuming this is just naturally occurred from them sitting in the box & touching the metal. I attempted to clean the laces but it only lifted slightly. Laces are 47inch length if you want to swap them out for new ones, but tbh the discolouration isn’t visible once the laces are tightened.
