Mizuno SONIC IV MR (Multi Racer Model), model number: N2MB9002. Used in one race and not tried on otherwise. Due to aging, the inner print is fading, even though it was stored neatly in a chest of drawers as shown in the first picture. The size is definitely M, so no worries. Since it was used only once, I've marked it as "Like New." There are no tears or stains, but the string is slightly frayed. The box is not included. FINA approved model. How about it for race-pace training or light races? When wearing, we recommend wearing a swim jack and dedicated gloves, and putting on the swimsuit. After the race, it was rinsed with water and dried indoors. Please refrain from purchasing if you are sensitive to used items. Please understand that this is a used item. When shipping, we will take care to prevent damage to this delicate item. Returns and exchanges are not accepted to prevent swapping. I will accept some price reductions, so feel free to comment.
