Baby's First Tooth and First Curl silver heart keepsake box set

The 2nd of 2 similar items I'm selling for my SIL. This very sweet set is sealed in its original packaging and consists of two silver plated heart shaped boxes, one for preserving a baby's first tooth the other for a lock of baby's hair. I am fairly confident the brand is Stephan Baby, but I'm not going to tear into the plastic in order to confirm. The design seems to have been discontinued by the manufacturer as I cannot find it online anywhere else. Each box is labelled and decorated with a small crown and pastel colored hearts.
