Under-sink faucet attachment A 400mm pipe with a 16mm outer diameter that can be freely adjusted in direction. - Pipe outer diameter: 16 mm - Length: 400 mm - Water discharge direction: Adjustable Thank you for viewing. I purchased this today, but it doesn't fit my home faucet, and returns are not accepted, so I am selling it. This is an upward-facing faucet attachment type. Please note that it did not fit because my faucet is a downward-facing type. This is a new, unused item that has not had water run through it. It cost 3080 yen.
