The thickness of the metal is excellent and will completely curl when struck. No help is required to make and maintain the shape. The silicone completely covers the metal. Silicone provides a non-slip feel and fully covers all metal parts. VERY good product. If you want to customize, you don't know what kind of paint or marker is needed to stick. The permanent marker works, but lets the silicone paint bleed through the first time you apply it.
