New MSR Trail Base Water Filter Kit [Japan Official]

Purchased 3 years ago as a disaster preparedness item, but now that my family has downsized, it's too large, so I'm selling it.

The silicone pump has some yellowing and discoloration, which is characteristic of silicone, and the hose is sticky, but I believe it is still functional.
Please only purchase if you understand that this is a pre-owned item.

Suggested Retail Price: ¥24,300

*Excerpt from MSR HP:

This water filter combines the portability of the TrailShot Microfilter with the convenience of the AutoFlow Gravity Microfilter.
Its most notable feature is its adaptability to various activities, from the trail to base camp.
On the trail, the main unit, which integrates the pump and filter, can be used as a hand-pump water filter.
At the campsite, it can be used as a gravity-fed water filter to purify a large volume of water at once.
The hollow fiber membrane filter has passed the NSF protocol p231, a drinking water standard test conducted by a third-party organization using water in the worst possible condition.
It can be self-cleaned in the field.
MSR reigns as a pioneer in developing innovative water filters for a wide range of outdoor enthusiasts.
With its world-class water research laboratory in-house, the company delivers innovative products that others cannot replicate.
The TrailBase Water Filter Kit is a water filter with the versatility and MSR's safety and quality standards.

*Note: Due to differences in shape, the TrailShot Microfilter cannot be connected to a reservoir for use.
