A 52-model acetate optical series curated across six verified batches of the current catalogue. Four real representative frames explore colour depth, bold volume, bridge geometry and faceted edges. Two labelled enlarged details show YD1594 colour contrast and YD1635 edge geometry; these details illustrate the named examples, not a feature claimed for every model. All 52 reviewed styles are linked. The catalogue includes newly listed and refreshed existing models. More styles: open this Collection product link.
