HEADS UP - There is a 30 minute Cart Reserve

To ensure everyone has a fair opportunity to purchase my limited-stock items, items in your cart will be reserved for 30 minutes. After this time, they’ll automatically return to inventory if not purchased.
Thank you for understanding and for supporting my work—I’m grateful to share these unique pieces with all of you!
