Description: The Mineral Wax Twins–Clean & Good were a registered Trade Mark of Columbia Carbon Co. and appear on many of their ribbon tins. It seems the company started out in Dayton & later moved to Los Angeles or they had a major office there.
The curved shields are that way to fit the roller’s shape. The 2 small green ones have a felt strip glued on the back, they also have word measuring markings and were made by 2 different manufacturers: Western Can Co.(S. F., CA) & Roc-O-Way Co., also S. F.
