Shungite bracelets are created on a stretch cord that is tied off, Shungite beads are 8 mm, standard size is 7″. If you need a different size/sizes please leave a note through PayPal.
To find out what size is needed use a sewing measuring tape, put it firmly, not tight, around the wrist. Do not leave any slack, the stretch cord will be too big. If you do not have a measuring tape use a stretch bracelet you already own or some bracelet that fits firmly and measure it with a ruler.
