Back in January or February of 2017, I was doing research on Pentel pencils and came across a website (I have since lost the website) that was a catalog listing of office supplies available (looked to be a wholesale distributor site). They had 4 P209 pencils I had never heard of.
In April 2017, I was referred to a website (www.ipenstore.com) where I purchased several of these pencils.
These are the Metallic P209s that have been released in the United States.
P209M-KX Metallic Blue Green
P209M-NX Metallic Graphite
P209M-PX Metallic Pink
One thing I wish that Pentel would do, is to standardize the color codes for their pencils, as it would make cataloging simpler. For example, the Metallic Graphite is different for the 3 different sizes that have been released. They are P205MNX, P207MN and now P209M-NX. The Silver (with Black text) are P205-MZX, P207Z and P209M-ZX.
