In the world of corporate gifting, few items hold as much meaning, elegance, and symbolic value as a finely crafted Italian diary. It’s more than just a practical tool – it’s a statement. A reflection of a brand’s identity, values, and attention to detail.
At S.D. Theofylaktos S.A., we have been proud ambassadors of this philosophy for over 30 years. Our reputation as a trusted provider of premium business gifts has been built on our exclusive global partnership with one of the most prestigious names in Italian craftsmanship: Castelli Milano 1938.
A Partnership Rooted in Heritage and Vision
Our collaboration with Castelli SPA is far more than a standard supply chain agreement. It is a partnership rooted in shared values: attention to detail, uncompromising quality, and a passion for innovation through tradition.
Castelli is a historic Italian brand known across the world for its artisanal bookbinding, luxurious textures, and design innovation. Each product in the Castelli Milano line reflects the legacy of Italian craftsmanship — and the forward-thinking elegance that modern corporate gifts demand.
As exclusive partners, we bring this quality to the Greek and international B2B market — giving businesses the opportunity to offer diaries that make a true statement.
Eco-Conscious Elegance: Where Innovation Meets Sustainability
Corporate gifting today must balance aesthetics with purpose. That’s why many of our clients seek sustainable solutions that align with their company values.
Together with Castelli, we proudly offer eco-friendly corporate diaries through groundbreaking materials such as:
- Appeel™: premium paper made from apple peel waste
- Biogreen: crafted from agricultural byproducts
- PETA-Approved Vegan covers: offering luxury without compromise
These materials do not sacrifice quality — instead, they elevate it. When you choose sustainable gifting, your brand sends a powerful message: we care about people and the planet.
The Executive Touch: Customization at the Highest Level
A corporate diary should do more than mark days — it should represent your brand.
That’s why we offer full personalization options through our collaboration with Castelli Milano. From foil stamping and debossed logos, to bespoke covers and custom layouts, each diary is crafted with your business needs in mind.
Whether you’re gifting top-tier clients, internal teams, or high-level stakeholders, these diaries offer an experience — not just a product.
Some of our most in-demand options include:
- Soft-touch vegan leather covers
- Metallic or textured finishing
- Fully customized inserts and packaging
- Exclusive Executive Gifting Sets combining Castelli diaries with pens or tech accessories
A Diary That Reflects the Quality of Your Brand
When your logo is embossed on a Castelli diary, it becomes a symbol of commitment — to quality, to innovation, and to timeless European style. It shows your clients and employees that your company doesn’t settle for less.

They’re not just gifting a notebook. They’re delivering a message of prestige.
