Gift Wrap
We offer a professional giftwrap service to complement your pen or leather journal. Simply check the giftwrap option on the product page before you add to basket (a charge of £3.25 will be added).
We use a premium silver giftwrap paper with a subtle two-tone patterned effect, and a hand tied silver ribbon. We also include a matching gift tag, which can be appended with a message of your choice. Simply add your message to the text box when you reach your basket. Items are giftwrapped individually i.e. if you order several items only the specific item requested will be wrapped.
We do not include any paperwork inside the giftwrapped item. If you select a different delivery name to your billing details, we add a gift receipt which hides all prices.
Nib size guide
- Smooth steady ink flow
- Distinct line variances
- EF particularly fine
Drawing inspiration from the timeless elegance of marble, the ECO Carrara with Onyx edition pairs a striking white marbled cap with deep onyx-black accents for a bold monochrome contrast. The clear demonstrator barrel reveals both the ink supply and piston mechanism, showcasing the precision engineering that defines TWSBI. The cap’s marbled resin evokes the smooth, veined beauty of Carrara stone, finished with polished black hardware and the signature TWSBI red emblem on the finial. The stainless steel nib, plated in black, offers a dependable and consistent writing experience, balancing smooth ink flow with subtle feedback. Equipped with a high-capacity piston-fill system, the ECO Carrara with Onyx ensures fewer interruptions during long writing sessions. A screw-on cap with rubber O-ring provides a secure seal, preventing leaks and evaporation.
As with all ECO models, the pen can be fully disassembled for cleaning and maintenance (tools included), though TWSBI recommends this only for experienced users.
