Ooooh! Thanks for posting this. Very interesting. So, it's essentially a planetes with a strap?
I was JUST looking at this! It's like a Cuir in Planetes material. I like this bag. It looks too much like my black Planetes to justify getting it in black and I really need to see the poppy in person. If it came in yellow, I'd be all over it for summer.
Looks a lot like LP Cuir design with Planétes materials. Might be worth looking into, especially if they start making it in different colors at some point!
