UPDATE: I have a newer version here.

We need coffee to sharpen our senses, but we need that same precision to make the coffee in the first place. It's a classic catch-22.

Introducing a dosing ring funnel tool that ensures your espresso grounds end up exactly where they need to be.

This tool is designed to fit a standard commercial size portafilter (58mm).

Dimensions: 75.3mm x 29mm.
Features contoured walls for better grip and reduced slipping.

Please note, I only offer the 58mm size, as that's the only portafilter size I have for designing.
