Weihnachts-Kerzen Christmas Tree Candle Holders

Weihnachts-Kerzen box of Christmas tree candle holders. These look to be wartime or pre-war as the Greif Chemie company didn't exist after the war (it was folded into another company with a different name). They were originally meant to hold 20 pieces but that has been crossed out and remarked for 16 pieces. This box was found inside a larger box with more clips. There are a total of 21 clips. The clip itself measures about 1 3/4'.
