Here is a Pentel pencil that is no longer being made. I have a few in my collection but it has not been one of my favorite Pentels. In the 1982 Pentel Catalog they show a black P225 with a blue P227 and a yellow P229. It appears that the P227 and P229 were not kept in the line up and are very hard to find.
Now I find that the P225 came in more then one color. Here is the red pencil. The standard black P225 is very popular among collectors but I like the colors. I am still looking for the P227 and the P229. Add them all to your collection.
