The Full Ultem edition is machined from a solid Ultem bar. Lightweight yet remarkably durable, it’s built for everyday carry without compromise. Free from logos and unnecessary distractions, the pen allows the natural transparency of Ultem to take centre stage, creating a modern, technical aesthetic balanced by Ajoto’s timeless minimalism and clean lines.
The Aluminium edition is machined from high-grade aluminium, adding reassuring weight and solidity. Its Ultem mechanism introduces a striking contrast between silver and amber, a contemporary interplay of materials that feels both functional and expressive.
Whether you’re jotting notes or sketching ideas, each pen delivers precision, durability, and a uniquely satisfying writing experience in a material unlike anything else.
What is ULTEM?
ULTEM® is a high-performance thermoplastic resin known for its exceptional strength, durability, and refined finish. Originally developed for demanding industries like aerospace and medical devices, this advanced resin is valued for its ability to withstand heat, impact, and daily wear without losing its shape or integrity.
So what makes it special for a pen?
Because ULTEM is an engineered resin, it’s incredibly tough yet lightweight. It resists cracking, warping, and scratching far better than standard plastics. It also has excellent heat and chemical resistance, meaning it won’t soften in a hot car or degrade over time from skin oils and everyday use.
Beyond performance, ULTEM has a distinctive look — naturally amber-transparent with a warm, glass-like depth. That clarity is a hallmark of this advanced resin and gives each pen a modern, technical aesthetic while maintaining a comfortable, balanced feel in hand.
In short, ULTEM isn’t just another plastic — it’s a precision-engineered resin chosen for its strength, stability, and longevity. It allows us to create a pen that feels solid, performs reliably, and is built to last for years of daily writing.
