Bought some ebay nappies from ebay described as used a few times and in excellent condition. Thry arrived today and al the flipsl have relaxed elastics one has mold stains and they are all stinking of what I can only describe as a salmony smell

. There was 2 other nappies in the bundle and they are perfect ( after a good wash) . I dont really want to return as the 2 good ones are two I was really after. But also not impressed at all at the condition of the others . Im planning on messaging thr seller but dont know where to start im rubbish at confrontation and don't want to offend her. Wwyd or rather say ?
