$HSN$9611$$ Designs By Ryn stamps are made from natural gum rubber and are deeply etched into the surface. Deep etch technology captures a high level of detail in each design and ensures clean imprints by setting the image at a depth that is twice the industry standard. Natural gum rubber is also extremely durable and flexible making it ideal for use on a variety of materials. With proper care each stamp can be printed hundreds of times without losing image quality. These are handcut unmounted rubber stamps.
