These antique nailhead beads measure 5.5mm. You really have to see these in person to appreciate their rare outstanding bright yet slightly transparent orange color and design. They are listed as transparent, but let me clear this up for you. They are actually a translucent color. Outstanding orange is the name we should have used. These beauties are domed smooth and the backside is flat. They are from the early 1900's. Glass nailhead beads were used in the days of the flapper to embellish garments before sequins were developed. You will receive 48 beads per lot.
