Vintage Altar Bell
This is a vintage bell.
Bells have been a witchy tool for a very long time.
You can ring a bell to cleanse a space.
Bells can also be used to seal spell work. Simply ring the bell after. They are also amazing for meditation. Start meditation with the ringing of a bell, and end with the ringing.
Bells have also been used historically for protecting homes.
I personally keep a bell on my altar at all times.
