Context: Only the front is pictured in the site , and nowhere on there does it mention the stain - ish marks on the back . It looks like food crumbs that were smeared and stuck , but they 're fairly faint . I suppose it 's possible the seller did n't see them if they never looked at the back but I do n't know .

Answer:
