Needless to say, I got home and found it online.
I love the small overall footprint of the case, and it's functionality. You take out the Velcro-d dividers that make it into four compartments and use just the space inside for your 24-marker wallets. Hers were folded with the marker colors exposed so you could see what was where.
I do have the clear plastic 72-marker clear cases for my markers; and those are lovely for being at home — but too often, I'm traveling with my markers, whether to friends or to teach. I had stacked them into my rolling tote; but having witnessed what happens to them when I used to ship that way for UPS for my classes – I want something more shatter-resistant! I just demoed in Manhattan a couple weeks ago and between trains, taxis and pedestrian traffic; I'm lucky those plastic cases survived.
