Vtg Chinese Filigree bracelet with Carved Bone

Such a neat piece! Selling for a friend who received this as a gift from a much older friend many years ago 😂 (she's 80). Her best guess is that this is circa the 1920' or 30's. The 3 panels are depicting the chores of life as best I can tell. Measures 7 1/4" long. Each panel is 1 1/2" high and the thinner part where it clasps is 3/4" high.please see pictures for signs of wear
