Unused "SCORKL" - A portable oxygen tank that allows you to swim underwater without needing to carry anything on your back. Easy diving!

【Unused!】 SCORKL Oxygen Tank for Swimming Without Needing to Carry on Your Back / With Hard Case
-------
This is a revolutionary device that allows you to enjoy diving easily without having to carry a tank on your back! I bought two sets for my husband and myself, thinking it was groundbreaking. However, around the same time, we became heavily into surfing, and our trips to the ocean were solely for surfing. We never had the opportunity to go snorkeling or diving, so they ended up unused and stored away in our storage room (TT).
They have been carefully stored and are in truly beautiful condition.
(Photos: The first three photos are from the website, and the photos from the fourth onwards are of the actual product.)
I don't remember the exact price, but the full set for two people, including the cases and pumps, cost around 100,000 yen...
I really wanted to use them, but since we end up surfing whenever we go to the ocean, it seems unlikely we'll have a chance to use them in the future. Regrettably, I'm listing them in hopes that someone else can use them.
The contents include: 2 sets of oxygen tanks, 1 set of manual pumps, and 1 hard case (as shown in the photos).
*We plan to ship the contents inside the hard case. If you would also like the yellow outer box, it will be shipped separately, so we will increase the price slightly to cover the additional shipping costs. We will list the box separately, so please purchase that as well if you want it.

Below is a description from the product website:

SCORKL is a device that allows you to dive by holding a small tank directly in your mouth. The regulator and mouthpiece that control air pressure are integrated with the tank, so this is the only equipment you need.
Compared to regular scuba diving, where you have to carry a tank on your back, this is overwhelmingly lighter and less hassle. Swimming with a heavy tank on your back requires skill to maintain balance. This tank is small and light, allowing you to swim more freely underwater.
You can dive for about 10 minutes on one tank. The remaining air can be checked with a meter, allowing you to enjoy underwater swimming with peace of mind.
It's also convenient to refill the air. Tanks used for regular scuba diving require specialized equipment for refilling, making it difficult for individuals to own them. However, with SCORKL, you can use a dedicated pump-style inflator. It works similarly to a bicycle pump. It also has a function to filter out moisture and impurities.
