These pens are indeed great but be warned... they are the exact same as the
Sakura Glaze pens! If you already have the set of 10 Glaze pens, then you
already have these pens. Same colors, same tip thickness, everything.
They were probably just marketed under a different name in Japan...
And also, as with the Glaze pens, they write on just about anything... in case
you were wondering.
