Elfen is a part of D.H.A. Siamwalla Ltd., a centenarian firm, established in Bangkok, Thailand since 1907. Our general stationery manufacturing history dated back to the 1930’s, and files manufacturing in particular, to the 1960’s. We were the first in Asia, to have in-house metal components manufacturing, and in-house plastic film extrusion for PP lining materials. Hence, while others follow, Elfen has led and started the trend towards more economic price level for Polypropylene-based products and significantly improve health safety for consumers, and contribute to better care of our planet earth.
