The Brass Wren is a refillable writing pen crafted from brass, designed to improve with age. It uses cotton cores which you dip into any fountain pen ink. Weighing 53g, it offers a solid, balanced feel, twice the weight of the standard Wren. Equipped with a precise Japanese-made tip, it delivers smooth writing. Made in the UK with expert machining, this durable pen is perfect for those who appreciate quality and longevity in their writing tools.
What ink can I use?
The Wren is compatible with dye-based Fountain Pen Inks, so long as they don’t contain particles (such as shimmer inks) or binders (like acrylic or shellac).
