This is a bag that was used at a swimming school. There are some scratches on the card slots, but overall, I think there isn't much noticeable dirt (*^^*) It has a mesh pocket inside, so you can put small items like your wallet and phone without them getting wet☆ It's durable, so you can use it for school pools, leisure activities, or just as a regular bag (*^^*) It's a cross-body type. It also has reflective tape for safety☆ Adult women can use it. Small men can use it too! It's big enough to hold a full set of swimming gear. Bag body only, without the belt (The shape is complex, so these are approximate dimensions, please understand☆) 40cm x 31cm Thickness 14cm I will sell it to someone who understands that this is a personal inspection (*^^*)
