ABSTRACT:
A case for holding and dispensing small components such as orthodontic O-rings. Most of the component is fictionally or otherwise retained within the case, and only a small component portion extends from the case to be accessible to and grasped by the tips of a plier-like extraction tool. The case prevents the tool tips from closing over the entire component which would require component repositioning before placement.
