Vintage Mid-Century 4 Strand White Faux Pearl Graduated Beaded Necklace

1950s or 1960s 4 strand beaded white necklace with a gold tone J clasp. Graduated plastic beads from 16mm to 8mm in size. The shorter strand measures about 12 inches not counting the tail. The longest strand measures about 17 inches. The tail is about 1 3/4 inches long. The round plastic beads alternate between shiny and dull and are separated by white plastic spacers. Double cord is used for the stringing. I believe it to be cotton cord. In very good vintage condition. The clasp is marked JAPAN. JB 004-35
