Underwater mask & Tuba

We bought this mask and tuba to teach our son how to swim underwater. It’s fun and safe. It’s been sitting in the closet for a while, it will need a cleanup, but it’s in great condition Adjustable straps behind the head. The tuba goes on top of the mask. Size XS, 3 or 4 years old Bought at Decathlon Please look at the pictures carefully and ask any questions before buying. I’m always happy to answer questions!
