## Notes

Breville's own 58mm bottomless (naked) portafilter, for its 58mm machines —
the Dual Boiler, Oracle and Oracle Touch. Removing the spout lets you watch
the extraction and spot channeling. Breville makes this only in 58mm; the 54mm
Barista/Bambino machines are a different size and this does not fit them.
