This new collection provides a viewing access to Delta's famous and treasured side lever filling system.
Upon continuous requests from pen collectors all over the world for the very popular and sold out Colosseum limited edition collection, Delta decided to create this new collection.

The Colosseum demonstrator collection offers both the look, and elegance of the Colosseum and at the same time allows collectors to admire, study the very complex lateral lever filling mechanism, and appreciate all the detailed work involved in its manufacture.

The Colosseum demonstrator fountain and ballpoint pens are hand-turned from solid bars of clear, yellow and black resins. In order to produce the extra clear see-through body painstaking hands on work is needed. The central ring is in solid sterling silver and it is hand carved with the famous Roman ivy shaped leaves.
