Kids' Penguin Swim Ring Purchased for a trip and used only once. Since my child has grown and won't be using it anymore, I'm decluttering. *For confirmation, I inflated it and left it for a day, but there were no signs of air leakage. *Although used only once, there are some dark stains as shown in the photos. I washed and wiped it with disinfectant wipes, but they didn't come off, so I believe they are inside the swim ring. Thank you for your understanding. Children grow quickly and outgrow things, so I think this item is perfect if you consider it a one- or two-time use item. Shipping will be done anonymously via Rakuraku Mercari Bin or Yuuyu Mercari Bin. Basically, I can ship it on the same day or the next day, unless it's late at night. #Penguin #SwimRing #SwimRing #FloatationDevice #FloatationDevice #Float #WaterPlay #PoolPlay #Pool #Sea #Summer #Outdoor #Travel #WaterPlay #Cute #Child #Baby #Kids
