What is the purpose of these omamori/charm?

I purchased 2 omamori from Kumano Hongu Taisha for gift, but completely forgotten what these are for. I remember one is for health and another one is for protection, but I may be wrong.

Does the writing on these omamori give any clue? Much appreciated for the help!

Thank you.

Blue with black crows protect you from bad curse.
White with black crows and Gold Bold provide you good healing of your heart and body.

Black Crows at Kumano Hongu Taisha means spiritual icon when they invited the Emperor Jimmu to Nara. Now black crows are spiritual icon for inviting you to good way.
Those black crows are told that they have three legs, which means, heaven, land and human, all are from the sun. Therefore Omamori printed black crows.

Thank you very much! It really helps!

Where can i buy those? I seriously want to buy them.

As mentioned above, I got it from Kumano Hongu Taisha.
