"I Castoni" by Stipula offers an unusual combination between a writing instrument and precious stones. Cabochons of onyx, agate, ruby, lapis lazuli, tiger's eye and many other gems are selected and set in a touchstone pen that speaks of high quality materials and workmanship.
The Italian firm Stipula is based in Florence, cradle of artists and craftsmen. It recovers the tradition of using Celluloid, a very unstable and difficult material to manufacture, but once achieved it is very attractive, non-allergic and very durable. His creations are very balanced and use noble materials such as silver and gold, with other more modern ones such as titanium.
