I'm not sure of the pricing on the Spirited Away pieces, but I remember seeing a lengthy thread on this collection here in the Loewe subforum. I would search there and see what you find.
If you cannot keep both, I would keep the one on the right and look at adding the bag on the left later. I think the left one will continue to be available, and will be easier to find on the pre-loved market if Loewe decides to discontinue this style/color.
Thank you so much for your input! ❤️❤️
