Custom notebooks.

Make your brand impossible to ignore.

Custom Notebooks

Notebooks are more than objects. They are idea warehouses and powerful brand ambassadors. Trusted by global names like the

Whitney Museum and

Herman Miller
we design custom pieces that fuse purpose with product design.

We received the notebook packages last week, they look really great! Thank you and your team for the hard work. We look forward to using them as goodies for our events. 

They are gorgeous…BE-YOND! Thank you!!!! You are such a wonderful partner to the museum.

Our experience with mishmash has been great. The team is easy to communicate with, quick to respond, and excellent at working through details with us. We made a few tweaks along the way, and they were always happy to help until everything looked exactly the way we wanted.

Fully bespoke.

No shortcuts.

You’re not choosing from an off-the-shelf catalogue. We’re building a product from the ground up. Every detail is tailored to your brand.

Designed locally.

Made in Portugal.

By keeping production close, we ensure full control, consistent quality, and attention to detail. The result is superior materials, refined finishing, and products that feel as good as they look.

From idea to delivery, handled end-to-end.

We consistently maintain close oversight and thorough follow-up on every step.

Share your idea

Bring us a brief, a concept, or simply a direction. We’ll take it from there, shaping it into a fully developed product aligned with your vision.

Co-create the concept

We work with you from brief, concept, or direction to shape your idea. We refine, challenge, and elevate it until it becomes its strongest version.

Custom design & mockups

We develop mock-ups and proposals to ensure the result is exactly what you envisioned so you see precisely what you’re getting before it starts.

Production & quality control

Not only do we design the products, but you can also expect a turn-key solution with full production support, where every detail is monitored carefully.

Delivered, ready to use

Packaged, labelled, and ready for your team, clients, or events. Delivered through a hassle-free process that takes your idea to reality.

Sent with love

Together with our trusted carriers, we ensure on-time delivery via both sea and air, so your project always arrives when it’s most needed.

Designed for brands across industries.

From museums to global brands, each project is built with a specific purpose: retail, internal use, events, or brand storytelling.

I received the ones sent ahead and they look great. Just in time for the museum members and events this weekend!

The notepads are going down very well (thanks for your efforts) and I see people with them already, they will get used across all channels. Thanks for your great efforts.

I’m really happy with the outcome! Thank you so much for bringing my vision to life! I truly appreciate everything you guys have done to make this process seamless and wonderful. Can’t wait to receive the rest and I hope this is only one of many more collaborations with you to come!

Happy and trusted partners.
