FLEXTAILGEAR TINY PUMP Portable Air Pump 1300mAh Battery 13.5W USB Rechargeable Ultra-lightweight Pump

Last year, I purchased the snorkeling tube from Sports Xenio and the air pump from Amazon.
I used them only once for a short time in Okinawa.
I washed them thoroughly and stored them, so there are no noticeable stains, but they have been stored at home, so they are not perfect.

The air pump also includes everything shown in the photos. I purchased it from Amazon, so it should be almost the same as what is currently sold, and I believe you will understand how to use it.

Thank you!
