Materials and Features:

• Extruded Acrylic Tube Composition: A classic example of 1960s space-age Mod fashion engineering. This features lightweight, hollow-core oblong tube beads crafted from premium extruded acrylic polymer. The material undergoes intensive factory barrel-tumbling to create a "super duper smooth" surface finish with completely flush, near-invisible mold lines that glide effortlessly against the skin.

• Vitreous Glass Seed Spacers: Alternating with the long acrylic blocks are genuine, solid white glass seed beads. Hand-verified via traditional dental texture testing, these hard, vitreous spacers feature an absolute absence of seam lines, providing a dense structural break that prevents the acrylic tubes from friction wearing against each other.

• Doubled Hand-Stringing Architecture: The massive 55-inch flapper length is meticulously hand-strung using a heavy, doubled silk-blend thread. This double-strand reinforcement distributes the pulling tension evenly along the rope, eliminating sagging and ensuring structural durability during versatile styling or layering.

• Mismatched Factory End Assemblies: The reverse mechanics showcase authentic, unmanipulated mid-century export production. Both ends utilize identical stamped industrial wire-guard crimp tips from the factory, combining a non-magnetic brass alloy gold-tone fold-over clasp with a contrasting silver-tone jump ring loop to reflect the rapid boutique assembly lines of the era.

Type: 55-inch flapper rope necklace with non-magnetic fold-over clasp and wire-guard end-tips

Age/Origin: 1960s (Mod Explosion Era / British Crown Colony of Hong Kong)

Marks: HONG KONG (Die-stamped into the interior lever of the fold-over clasp)

Measurements:

• Weight: 27.9g

• Dimensions: Approx. 55” total linear length

• Thickness: Oblong acrylic tube beads measure approx. 5mm in diameter

Condition: Great vintage archival condition. The extruded navy blue and white acrylic beads remain perfectly glossy and uniform with zero surface dulling, deep scratches, or chemical clouding. The original doubled stringing remains highly rigid and secure with no fraying, the internal plastic drilling burrs remain safely intact within the tube ends, and the brass fold-over clasp closes with firm mechanical security.
