A long Raksha sutra is so fine that it fits inside a tiny glass jar that is less than an inch long. The Raksha sutra is long enough to go around the wrist multiple times. To add to the design value, the sutra has tiny beads at regular intervals. Raksha sutra is the original symbol of rakhi in India that signifies protection. Send this rakhi to your brother if you intend to have a Raksha sutra on his wrist.
