In [[1928]] were resolved disputes with [[Parker]] for the use of [[button filler]], and were introduced four new celluloid models in for the [[Arumia|Arumia Original]] ''U'' series, where had been used a letter in the absence of a better brand, probably to indicate the initial for ''unbreakable''. Was also introduced a new line, the [[Meisterklasse|Arumia Meisterklasse]], more expensive. New models met with great success and at the end of the year the plants were operating at full capacity, and barely able to meet the demands.
