It was an honor and a privilege to be selected to make a pair of bags for Griffon Saddlebags (makers of excellent Magic Item cards). I broke my brain against the design for almost two months before they were finally done but all that effort made some gorgeous bags. Each one has a matching shoulderstrap and a pair of removable backpack straps. The buckles are a little fiddly but only necessary when the bag's in "backpack mode". I'm told one of these bags is on its way to feature in an upcoming episode of Critical Role on 12 March! So I'll definitely be watching for that! ^_^
In the meantime, if you're the sort who likes D&D props or just good art you should take a gander at Griffon Saddlebags. Those cards are top notch!
