I do like the idea that I do not have them all. So true with these great side clickers. Here on the left we have a PD325 and on the right is the PD345. As you can see the PD325 has a wider clip and a longer eraser. The eraser is so long that the blue caps will not fit on them. This one is black with a white side clicker.
This pencil was not found in some far off part of the world but right here in the US. I never saw them. Add one to your collection.
