■ Thank you for viewing. Please be sure to check the profile before considering or purchasing. ☆ Brand new, unused item ☆ I have opened it once for confirmation and then repackaged it. Please refrain from purchasing if you are nervous about this. I purchased it through personal import from an overseas outdoor shop, but I have never used it and it has been in storage, so I am selling it. A Swiss water purifier manufacturer's product that can be used in emergencies such as disasters. This model is no longer sold, so if you have used it in the past, how about it? I think it can also be used for camping. ※ The sponge has deteriorated because it has been in storage for a long time.
