We are engineers with over 40 years of combined experience in industrial design and manufacturing. From concept to sample, we have you covered.


We produce the highest quality products at the lowest prices. Our partner factories build to our specifications, and we manage the entire development process. You’re free to focus on what matters to your business, like your bottom line.


We handle every aspect of shipping, from the international brokerage to any logistical challenges. That means that your products arrive on time, stress-free. Guaranteed.

Inventory Management

We can work with your forecasts so that you get the financial benefits of inventory holding and the peace of mind that comes from having your products stored in the United States or internationally.

Promotional Products

Sometimes people need a little push before they’re ready to say yes.
Go beyond discounts with a promotional product your prospects can’t resist.


We can recreate vintage pieces or fashion something that your clients will want to proudly display. Never worry about patent infringement again—everything we make is thoroughly vetted and legally yours.


Get more visibility for your business with our branded Bluetooth speakers, multipurpose batteries, phone chargers, and more.


We’ve been commissioned to manufacture refrigerators, grills, and microwaves, but our factories can make any appliance. Let us bring your vision to life and your brand into your client’s everyday experience.

Your One-Stop Shop

At 4J international, we design and manufacture innovative, high-quality products that your customers will love. If you can name it, we can take it from there. And everything we make comes with a one-year warranty and lifetime service.

High Quality. High Touch. Low Cost

Your Idea Or Ours.
Fully Realized.

From concept to delivery, we’ve got you covered. As industry experts and innovators with large-scale manufacturing capabilities, you can trust us to create and care for your inventory as if it were our own.

First, one of our lead designers will consult with you to determine what products will make the biggest impact on your bottom line. Then we’ll spring into action and create a prototype so that you can see, touch, and feel the product yourself.

Once you’ve placed your order, we take care of the quality control, international brokerage and shipping, and delivery. We can work within your forecasting budget and store your products safely in one in one of our warehouses, keeping them off your books yet easily accessible.

We’re innovators

We design, manufacture, and thoroughly vet products instead of just slapping your logo on something that your competitors already sell. Capture the spirit of your business and delight your clients with unique merchandise that sets your company apart.

We’re full-service

Enjoy the peace of mind that comes from knowing we’re handling your products from concept to delivery. Just tell us when to deliver—we’ll take care of the rest.

We provide high quality at low cost

Our clients have relied on us for high-quality, cost-effective promotional and industrial products since 2007. On one occasion, we cut the cost of an existing product by 50 percent. Another time, we reduced our client’s shipping damage from 60 percent to less than 10 percent. Let us show you what we can do for you.

Welcome to 4J International. If you can dream it, we can make it. Our team will help you set an objective and choose your tools, developing a plan for your new product launch.
