Branded Pens with Purpose
At Studio GBM, we are always on the lookout for ways to combine quality, design and sustainability, and our branded Senator pens are a perfect example.
What Makes Senator Pens Sustainable
Senator pens set the standard for eco-conscious office essentials. According to Senator, each pen is produced using 100% renewable energy, reducing environmental impact from the very first step of production.
Every visible part is crafted from bio-based plastic derived from sugarcane, which Senator reports results in a significantly lower carbon footprint compared to imported alternatives. Senator states that its pens lead the industry in COâ‚‚ performance per metre of writing length.
Built to Last, Built for Your Brand
It is not just about sustainability. It is about style and flexibility too. Senator pens are known for their exceptional build quality and impressive writing power, lasting up to 5 years or 5 kilometres of writing, according to the manufacturer.
Best of all, they are fully customisable to match your brand. Whether it is ink in your exact Pantone shade or a crisp, clean logo, we ensure every detail reflects your identity.
