These are the perfect talisman to invoke good things for you. One side features the classic Celtic Shield Knot – the traditional symbol of protection and strength – while the other side has a Viking Bindrune we crafted to embody the qualities of strength, victory, protection and resilience. The runes incorporated in the bindrune are:
Uruz for strength and determination
Algiz for protection
Eihwaz for resilience
Wunjo for victory, joy, and gratitude
And -- if you want to keep your rune message to yourself -- then you can wear it with the Celtic Shield Knot design facing outward.
