The boxes continue to be popular to this day. Crummles and Company of England produced Snow White-themed pieces in the early 1990s. These examples are enameled on copper with hand-painted artwork. Under 2" in diameter. This first one was purchased from a gift shop in Cambridge.

While searching online for other boxes, I stumbled across this same Crummles enamel Snow White design being used on the whorl disc of a children's drop spindle.
Another box featuring Snow White with Dopey and Doc.
