Query: Red refills?

I have used PhD Multi Pens for years, they are more ergonomic and easier to grasp in my arthritic hand. I also love being able to switch back and forth between red & black pen and pencil and I do so often throughout my work day as a counselor. It is sometimes difficult to find the black refills so I am grateful to see them here. However, I have been unable to find the red for some time ... even asked PaperMate, who said they are not available. I'm on my last red refill, please help. If you know where to get the RED PaperMate Lubriglide refill #56408 please let me know at jodilivinthedream@gmail.com.
