Sadly, that Able Carry Thirteen bag has been discontinued. They've put out a new version where they cheaped out on the zippers, which are no longer waterproof zippers.
The Alpaka Pencil Case Pro just came in the post today. Have to say as an artist I love it, perfectly for carrying my on the go drawing essentials. It also fits perfectly into my into my TomToc EDC 5.5L Sling Bag along with my Paperblanks drawing book.
