Swimming Bracelet Material: Our swimming arm buoy is made of environmentally friendly PVC material, which is safe and durable. It's enlarged and thickened, highly resistant to pressure, and has an updated and sturdy load capacity. It's universally suitable for both adults and children. Independent Dual Airbag Wristband: The flotation device has two airbags, providing dual protection for children while swimming. If one airbag is punctured and leaks in the water, the other airbag can still provide stable protection. It is also more comfortable to wear and less likely to fall off the arm. Cartoon Floating Toddler Bracelet: Our inflatable floating armband is made with cute cartoon patterns that are not easy to fade, which is more in line with children's preferences and makes swimming more enjoyable. Portable Swimming Arm Boon: The swimming training and learning aid has an automatically closing inflation port, which is not prone to leaks and is safer. After the air is released, it folds back to its original shape, taking up no storage space. Ideal Gift: The water toy accessory comes in two different colors (blue and pink). Choose your favorite color and give it to friends or family as a Christmas gift, birthday gift, Valentine's Day gift, or other gifts. It is an ideal choice for all swimming enthusiasts.
