SHARK SHAPED - The diving mask is made of high-quality silicone, safe and non-toxic. Add elastic material and silicone sealing ring to fit your face better. The soft and adjustable headband prevents the mask from sliding and is easy to wear. The beautiful shark shape is especially suitable for children.
