Vintage White & Clear Plastic Retro Beaded Necklace
Unsure of age... Reminds me of 1980s 1990s era unless this is a modern necklace that is supposed to be that style... but it was part of an estate collection. Approx 29" - 30" in total length. 
No markings of identification. 
Pre-owned and used. As with the majority of my pre-owned jewelry this piece may need a quick cleaning.
