## Notes

The 15g size of VST's precision basket line — the smallest of the three sizes
(15/18/20g) that VST states fit most La Marzocco and Rancilio standard
portafilters, at 22.0mm depth per VST's own size table. Like all VST sizes,
it does not fit 54mm machines such as the Brevilles. Verified against the
official VST store page on 2026-07-04. See the 18g entry for the mid-size
variant.

The page's per-size table lists the 15g basket at 22.0mm height. Available in standard (ridged) and ridgeless versions. 'VST Filters DO NOT fit 49, 53 or 54mm portafilters.'
