The one on the left (the one they sent you recently? Imma just give my opinion using my eyeballs XD) is grained calf leather and the right is what Loewe calls "classic calf" - don't worry about the serial numbers too much, they've changed a lot and depend on the artisan (most recent Puzzles only have one tag, older have had two but I haven't gotten one with two in a hot minute).
What's weird to me is...they're honestly completely different products, because of the leather, this is very weird of Saks. What also throws me is the left is obviously a used and returned bag, judging from the handle and slouch? I'd keep the right (classic calf) as the structure is nice, the handle looks right and the stamping can change as they are handmade. If you use a conditioner, you won't get scratches/Loewe has care centres or will recommend one in your area if asked.
Anyone else have ideas? I'm running to look at my Puzzles now...XD
Thanks for your thoughts! When I said second, I was referring to the second order. I’m sorry I made this so confusing! In the picture with both bags, the one on the right is the used one. Which is also the classic calf. The one on the left is the new and pristine one, that looks like a grained leather. I’m puzzled as to how they are the same bags, but the leather looks so different! Another question is, is the handle of your puzzle stiff and maintains its shape? Or does it flatten out once you lay the on a flat surface?
