When you want to give the blessing of a long and healthy life, a Chai charm (Hebrew for "Life") is a perfect choice.
A Hebrew symbol, chai, dangles from a red string bendel bracelet, which is worn for good luck and protection.
Description card is included retelling the story behind the red string.
To prolong the life of the red thread, best to not get it wet.
I bought mine a while back when it was being sold for a fund raiser. I don't take it off. I love it. Beautiful. Not uncomfortable to sleep in, either.
I have purchased red string bracelets from AlefBet. I love them. They tune me into my mystical Jewish heritage. Makes me feel better at this time. They were so quick to send them. Excellent company
