Defying style, dimensionality and usability since 1986… I’ve found the duo-pen 626bc more practical than the single refill 606bc as it is easier to change the refills. The wilder designs with colored sprinkles are out of reach for now. And the suspicion that SEED provided the eraser guts for the 636eh is kinda confirmed as well.
Merry Christmas, everyone! 
I used to dismiss these as a gimmick design, but you know for nice quality notebook folders, the flat design of the 606 works so well. Great collection, Kelvin! I like how TOMBOW played with the silver/black/white motif.
Hey Kelvin,
Very, very nice set of 600 series! I’m envious.
I picked up this 636eh
Different and distinctive. That’s my motto.
One question though: When you say that “…SEED provided the eraser guts…”, what does that mean?
cheers,

What I meant was that, as SEED was an eraser product company first, it was far more likely that they developed the mechanism and refill format for Tombow based on the 606 family’s design specifications.
In view of the very similar SEED Slendy+ I think that SEED does a lot more for Tombow:
By the way, Tombow’s MONO eraser is also made by SEED.
Thanks guys, I did not know this. I’ve never heard of SEED. Very cool.
Why do you all think that seed developed more for Tombow? Pencil mechanisms are quite far from eraser Production – the other way round ( tombow made the pencil for seed) sounds more plausible for me?
I wasn’t thinking about pencils, I just suspected that SEED not only manufactures the actual eraser for Tombow, but the complete product, i.e. in the case of the stick eraser shown, the casing, the mechanism and the eraser core.
Yes, this is what I was thinking too. The whole of the 636eh was developed by SEED for Tombow, who gave them the physical dimensions for the 606 line-up as a general spec. SEED would know how thin the eraser could be, how firm it needed to be, and how the mechanism would work. It was probably licensed for a period of 10 years (for example), after which SEED could use it for their own branded version.
