The pipette had a BB on the bulb, but I don't remember a T. When I PMed you the scans, you confirmed that it was Blue Balls.
I do not have Blue Balls, though I am assuming it is similar to Blue Ball Diamond which includes Blue Balls. Based on experience with Bright Blue and Blue Ball Diamond and given the described packaging, I think this is Bright Blue.
When you use broader nibs your scan shows a darker blue than what I could expect from Blue Ball Diamond. Additionally, the pipette was marked closer to how the Toucan Inks were than how the Susemai inks were.
Lack of the T on the pipette would not be too surprising. With no effort on my part to remove it, them the marker has disappeared (washed off in handling apparently) from my pipette.
