New MSR Water Filter AutoFlow XL Gravity Filter 10L Unused Item

I'm selling this because it's too large for solo trekking at 10L. It's unused and new, but it has been handled by someone before, so please only purchase if you understand this.
Suggested Retail Price: ¥19,800

*Excerpt from HP below*
This is a water purification system that uses gravity for automatic flow, eliminating the need for pumping. It can purify 10L of water at once, making it ideal for large groups or base camp use. The hollow fiber membrane filter has a purification capacity of 1.75L per minute and can be easily cleaned by backflushing (reversing the water flow). It comes with a universal bottle adapter that fits from large-opening reservoirs like the Dromedary bag to small-opening Platypus bottles, allowing for efficient access to clean water.
