It seems that "witchery product" can refer to a variety of products, including art materials, books on kitchen witchery, and skincare products. The search results include information about Stitch Witchery, a type of adhesive used in arts and crafts, as well as references to kitchen witchery books and skincare products from a brand called The Witchery CPH. The ingredients or materials of these products are not extensively covered in the search results. If you have a specific type of witchery product in mind, please provide more details so that I can offer a more targeted response.
