Great fun to wear a vintage 1960s necklace in cream plastic on string the closed tube shapes are 1 long and 34 dia and are actually made in 2 snap together halves with a pale gold coloured shiny plastic ring round the middle the round beads graduate from approx 38 to 34 at 32 long it certainly fits the swinging sixties the small dots you can see are the injection moulding feed point and one bead has a small line may be biro see photo
