I think you're spot on about this being one of strategy. This market is very crowded so it's important for them to continue to create demand. I do think they have some limits with respect to inventory because these bags are all handmade so scaling handmade labor has its limits. Still, the return policy is smart on their part because the demand is such that they don't want to mess with returns, especially with this kind of leather.
I didn't buy anything but I did poke around the site last night and there were still some bags available, so that does say something about their inventory going up --or demand leveling off--or a combination of the two.
I have a regular black/royal bucket and a mini camello/azzuro from last year and love them both. I would love to see the tumble tote but I want to see it in person before committing to such a purchase. All that said, it's nice to see a small brand succeed in an age of mass produced, expensive designer brands.
I too agree that it is a marketing strategy.
I am curious about your statement, "...because these bags are all handmade..." Aren't all bags handmade? These bags certainly are not handstitched like a Birkin. Are they? What do you mean?
