Universal pen holder V2: The metal pen holder with 3 locking screws can hold pens with a diameter of up to twelve millimetres. The shape of the pen must meet certain requirements (diameter of the shaft, tapered tip) to fit into the holder, so its suitability must be tested. The SLIDER ballpoint pen (always recommended!) and the STABILO POINT 88 fiber-tip pen, for example, can be used with both tips. This pen holder is suitable for CraftRobo CC100, CC200 CC300, CC330 and all Silhouette hobby plotters (SILHOUETTE CAMEO 1-3, silhouette portrait 1 & 2 and Silhouette Curio). Note: The pen holder is not compatible with Silhouette Cameo 4 and Portrait 3.
