About

So Genius I/O is a custom product shop built around creativity, personalization, and practical design. We create custom game pieces, tabletop accessories, organizers, and everyday solutions that are made to feel personal, useful, and different from what you can find on a shelf.

What started as a passion for 3D design, laser engraving, and making things by hand has grown into a shop focused on products that bring meaning to the table. From custom domino sets and card deck boxes to tabletop accessories and functional 3D printed pieces, every item is designed with care, purpose, and attention to detail.

Game pieces with meaning. Made for the table, the culture, and the people you play with.

Made by Hos

So Genius I/O is designed, made, and packaged by me, Hos, in Garfield, New Jersey. Every product starts with an idea, a problem to solve, or a design that deserves to exist. I handle the process from design to production, which means each order gets personal attention before it leaves the shop.

I believe good design should do more than look nice. It should serve a purpose, make life easier, spark conversation, and feel like it belongs to the person using it.

Why Dominoes?

Dominoes are more than a game. For a lot of families and communities, they are part of the culture. They show up at cookouts, holidays, family gatherings, barbershops, tournaments, and late-night game tables. They carry memories, competition, laughter, and pride.

That is why custom domino sets became such an important part of So Genius I/O. A domino set can represent where you are from, who you play with, what you love, or the people you want to celebrate. Whether it is a country, city, family name, team-inspired theme, fraternity, organization, logo, or personal design, the goal is to make each set feel meaningful before the first tile is played.

What Does So Genius I/O Mean?

The name So Genius I/O represents the connection between ideas and output. The “I/O” stands for input and output — taking an idea, request, sketch, problem, or inspiration and turning it into something real. It is about using creativity, technology, and hands-on work to bring custom products to life.

In simple terms: you bring the idea, and we help turn it into something you can use, gift, display, or bring to the table.

Custom Requests Welcome

If you do not see exactly what you are looking for, you can request a custom design. Customers can request designs based on countries, cities, cultural symbols, family names, logos, teams, fraternities, sororities, businesses, tournaments, events, or personal themes.

Custom requests work best when the idea is clear, bold, and meaningful. Simple logos, short phrases, names, initials, symbols, and clean artwork usually produce the best results for engraving and 3D printed products.

Made with Care

Every item in the shop is made to order with a focus on quality, function, and presentation. Some products are laser-etched, some are 3D printed, and some combine multiple materials and processes to create a finished piece that feels unique and useful.

Whether you are ordering a custom domino set, a card deck box, a game tray, or a practical everyday solution, the goal is the same: create something thoughtful, functional, and made with care.

Thanks for stopping by and supporting small business, custom design, and all things DIY.

Let’s build something great together.
