Our bobbleheads are made from a high quality, durable poly-resin material. With its highly customizable characteristics, poly-resin allows for the finished product to be highly detailed in all aspects of the design. Because of the increased time required for this process, many other companies use polymer clay instead. Clay is a cheaper and much more fragile substitute, and over time it will dry, crack, and break easily - while poly-resin won't crack or dry out, and is much more durable. Poly-resin is the material that quality commercial products are made from. It is the industry standard when it comes to producing bobblehead dolls. If you are going to spend the money to buy a custom bobblehead, why not get the best quality product possible?
