This pen holder is only suitable for the left tool head of the SILHOUETTE CAMEO 4 (PLUS/PRO) and for the Silhouette Portrait 3. This universal pen holder with three different plastic caps transforms your SILHOUETTE CAMEO 4 (PLUS/PRO) or your silhouette portrait 3 into a drawing machine. With the help of the three different clamping caps in blue (small), white (medium) and grey (large), it is easy to adapt to a wide range of pins. The clamping cap centres and clamps the pin as soon as it is screwed onto the base. A very high holding force and thus a firm fit of the pen is achieved. Fits pens with a diameter of 6.4 - 10 mm. Contents: 1 x pen holder, 3 x plastic caps
