Materials and Features:

• Premium Butterscotch Rhodoid Matrix: High-grade industrial cellulose acetate sheet stock manufactured by G. Convert SA in a dense, translucent butterscotch formulation. The structural composition delivers an ultra-light material-to-volume mass ratio that yields a bright, distinct acoustic clank resonance when handled or stacked.

• Suspension-Blended Milky Swirling: Features localized, low-density milky white swirling filaments beautifully embedded deep within the butterscotch core. This subtle, multi-layered marbling remains cleanly suspended underneath the mirror surface, revealing itself under directed illumination or magnification.

• Seamless Hand-Sculpted Architecture: Engineered as a continuous, flat-band solid loop completely devoid of automated lateral mold seams, split lines, or mechanical injection points. The unbroken perimeter maximizes light transmission and highlights the fluid movement of the internal swirling.

• Bench-Polished High-Gloss Finish: Finished with an exceptionally uniform, high-gloss mirror sheen across the entire band. The smooth, pockmark-free exterior surface is achieved entirely through meticulous factory hand-buffing using fine mid-century abrasives, requiring no superficial lacquers.

Type: Continuous solid-loop flat-band fashion bangle bracelet designed to slip over the hand.

Age/Origin: Circa 1950’s / Oyonnax, France (G. Convert SA Manufacturing)

Marks: Unsigned Factory Original (Verified via the distinct 17.2g mass metric, narrow 0.5" flat-band profile, and clean absence of industrial mold injection signatures).

Other: This piece serves as a textbook example of mid-century French artisan polymer craftsmanship. The item exhibits a definitive internal lamination footprint—a deep, subsurface material fold visible strictly under magnification—paired with a minor, localized hand-polishing tool skip line on the outer face that can be felt with a thumbnail, providing diagnostic proof that the bangle was hand-sculpted from pre-cast multi-layered Rhodoid sheets. The piece has successfully passed comprehensive structural screening, showing a negative chemical reaction to Simichrome testing and producing zero phenolic or camphor odors under localized thermal testing, confirming an immaculate, chemically stable cellulose polymer structure.

Measurements:

• Weight: 17.2g (Exhibits the classic featherlight mass density signature of authentic vintage European Rhodoid)

• Dimensions: Width: 0.5" Wide (12.7mm) | Cross-Sectional Thickness: 5mm Thick Flat-Band | Inside Opening Diameter: 2.625" (Standard comfortable vintage fit)

Condition: Very Good to Excellent vintage condition showing clear signs of gentle historic wear. The premium high-gloss mirror sheen remains beautifully preserved and uniform across the entire perimeter of the bangle, free of environmental degradation or clouding. The outer wall features a minor, localized factory bench-tool skip slash that can be felt with a thumbnail, alongside a faint subsurface lamination fold; these are authentic, non-structural manufacturing characteristics consistent with 1950s hand-sculpting from sheet polymer. The piece is entirely free of chips, cracks, post-market damage, or modern structural losses, with all comfort-rounded rims remaining perfectly intact.
