These beads measure 7mm x 2.5mm. Double strand round with a smooth front. These are very old and primative so the cuts are not as clean as contemporary beads. This makes these even more valuable to the collector. Yummy and unusual to come by. Made in Czechoslovakia. They are from the early 1900's. What a find! Glass nailhead beads were used in the days of the flapper to embellish garments before sequins were developed. You will receive 40 beautiful transparent blue antique nailhead beads per lot.
