Write a spell on a piece of paper... this can be an incantation or Invocation that you composed yourself, or copied from a book, website or other source, 

Roll the paper like a scroll, and use one of these metal bands to hold. 

So long as the spell is hand written, and one of these bands is around the paper, the spell will be strong,, powerful and have its intended effect. 

Due to the extreme potential of this offering, I must state that it should only be used with positive incantations, invocations, of positive intent, 

I have a limited amount of these available, as I am keeping several for spells that I a working with as well. 

Surely one or more of these will be a great asset unto thee,
