This omamori is for protection, made from Saidai-ji Nara Japan.
Omamori are Japanese amulets, charms, originally made from paper or wood items usually kept inside a brocade bag and may contain a prayer or religious inscription of invocation.
Omamori should never be opened in order to avoid losing their protective benefits and should belong only to one person. You can tied to a backpack, purse, car mirror etc.
Throwing an amulet in the trash is highly discouraged. Old omamori should not be placed in the trash with other commonly discarded rubbish but rather treated with respect.
