A holder for centered round articles comprises a frame having a first arm and a second arm pivotally attached thereto. The first arm defines a single contact point at its distal end while the second arm defines a pair of diverging surfaces at its distal end. The two arms are mechanically coupled to rotate relative to each other in a fixed relationship, and the curved surfaces on the second arm are shaped in a particular manner so that circular articles held by the two arms will be centered at a fixed location relative to the frame. |
