Item measures: 7-7.25" Beads measure 12mm. Strung on industrial-strength elastic. Because each bead is 100% handmade, there may be slight variations in size and shape. No two are exactly alike, making each bead as unique as the person wearing it. Clean Viva Beads with hot water and laundry detergent. Scrub clean with a small tooth brush and dry with a soft cloth.
