Gas Water Heater, Hot Water Shower, Propane Tank, Portable, Pet Shampoo, Camping

This is a water heater that can be used with cassette gas.
I purchased it a few months ago through crowdfunding.

Unlike suspicious overseas water heaters that appear in online ads, this is a well-made and functional product from a domestic manufacturer.
I bought it for use while surfing and in my camper van, but I've only used it 2-3 times as I ended up going to local hot springs more often, so I've decided to sell it. The scratches on the side are from rubbing against other items during transport in the camper van due to vibrations, but they do not affect its functionality in any way.
Portable water heaters are not commonly seen, so I considered keeping it for disaster preparedness or summer camping, but after considering how often I would actually use it, I've decided to let it go.
I think it would be useful for washing pets outdoors with warm water, even if you don't have an outdoor faucet at home.
As this is an expensive item, it would be best to inspect it in person and confirm its operation to prevent any issues. However, I have performed a full operational check myself, so I can also arrange for shipping if you are comfortable with that.
In the unlikely event of a functional defect, I cannot provide support, but there is a manufacturer's warranty until July 18th, so please contact them directly.

It's a bit pricey, but I believe it's worth the quality.
