I just picked up a 'Smiggle' pencil case - zippable, hardish case.
Looks smart and fits my stuff.
Thought I might need to modify it, but it works really well.
Can fit razors in pen holder.
Barber hone can fit underneath.
Small brush, styptic pencil and small mirror in interior pocket.
My shaving cream is in a tub and I can always fit in a shave stick in small plastic bag.
(Might post pic if I get around to it, but here's link:Smiggle : Hardtop Pencil Case - I got a black one.
I don't have any connections with Smiggle - I'm a teacher and had noticed my students' pencil cases...)
All the best,
Michael
