I'm mostly using the black walnut pedestal-bowl from my Le Tuft Urban Hermit's Black & Blues custom shave set.
I would love to also be able to source a couple or three, inexpensively procured Marvy unbreakable mugs. I know most people think they are ugly, but there's something about the heavy green rubber mug and the 'sandalwood' (IE: light brown) plastic one. I know Cosmetic Solutions, on amazon.co.uk sells the Marvy 'opal' plastic mugs but that would cost around £15.00 if I remember correctly.
