The modern Scribe pens from Recife, France, are made of proprietary resins from a renewable resource, The colors and shape are simple and ?modern?, yet they have a particularly weighty, balanced feel as a result of the solid brass interior. When you are ready to write you ?pop-off? the round tip-protector and snap it on the back of the pen with a satisfying ?click?. The ceramic rolleball produces a controlled black ink flow as responsive as a fine art drawing instrument. Long-lasting cartridges can be replaced, Guaranteed by Recife. A wonderful gift, especially when paired with a boxed stationery set.
