The unique design of the Limited Edition Arco series pens is a stratification of layers of materials, creating a design with colors that were popular in the ‘30s. After intensive research, Pineder has been able to replicate these famed hues with several layers of resin, creating a visual effect that mimics celluloid—a once popular material in pen manufacturing. This new resin is more durable and does not face the crystallization issues of celluloid, making the Arco an amazing upgrade. Only 888 ballpoints have been produced. Ballpoint uses Parker style ballpoint, gel, or Easy-Flow refills.
