Just tried it and it's a bit tight for comfort, I'm afraid. While it does technically fit into the tube, a tuft of hairs pokes out of the hole on top of the tube, and I have to tug on the knot fairly hard to get the brush out as it's such a tight fit. YMMV but I wouldn't be comfortable using the small Simpson travel case regularly for my T1.Someone said the Trafalgar 1 fits in the small Simpsons travel case- the one designed for the Classic 1, Duke 1, and the Case. Is it true? Will the T1 fit in the small tube?
