James Dean and the elusive EE pencil

One of the coolest souvenirs (okay, several  of them) that I brought back from Thailand was the Staedtler Mars Lumograph EE pencil. The majority of street artists there were using them and I am a magpie for art supplies...
It has a nice range of tones--including a very rich black-- depending on your hand pressure and it lays down nicely. Here is a sketch of this week's subject for Caricaturama, done with it:

In doing a little research on the internet, I found out that the EE might only be sold in Thailand and *may* be the same item as the 8B pencil. There are many listings online to buy all the other grades of Lumograph  pencil, from HB on up, but the EE seems to be very hard to find. Unless you're in

 a stationary store in Bangkok!
