What it does

Screws onto standard PET bottles for instant funneling
Frees you from a separate funnel and bottle
Saves cleanup at brewing or storage time
Brings flexible kitchen and shop tools to any home

Skip the separate funnel. This adapter screws onto a standard PET soda bottle, so any empty bottle becomes a working funnel for liquids you want to transfer cleanly. The kind of small tool that turns trash into utility.

Use for water, oil, juice, vinegar, or any liquid headed into a small-mouth container. Wash with hot soapy water between uses, and recycle the bottle when it gets dirty. Print extra adapters for the kitchen, garage, and shop.

A favorite for home brewers, picklers, and bulk-storage fans. The kind of upcycle that earns daily quiet use.
