Unused, but old. Upon a quick inspection, there doesn't seem to be any noticeable dirt, but the blue one shows some fading on the folded areas. I cannot determine the extent of any deterioration due to age. Please refrain from purchasing if you are concerned. Below are the approximate sizes for reference: Blue: Length 43cm, Width 31cm, Shoulder Width 27cm, Sleeve 12cm Yellow: Length 49cm, Width 36cm, Shoulder Width 32cm, Sleeve 14cm
