Hello and welcome to Wildwood Creations! This listing is for my personal homemade mixture of black salt which will be coming in a LARGE VIAL. If you would like a small vial of black sea salt, please see the corresponding listing. I use a special wood that I burn to ash that has protective, and banishment properties, once it is completely burned I mix it with pure sea salt. The small vials are 1.5 inches in height without the cork, and nearly an inch across. The large vials measure approximately 3 inches in length and 7/8ths of an inch in width. Thank you so much for stopping by and I hope you take the time to look through all the other things I have available in my shop!
