There are a number of key rings that can be made from any material that a pen can be made from. There are simple key fobs, and more complex key rings that can contain toothpicks, or even an assortment of small pills.
These are typiclly sold only at craft fairs. However, you can custom order one or an assortment by contacting me through my contact page.
Key holders made from various materials, in a variety of styles.
