Company Details

GS-JJ and my representative, Taina, are great to work with. Super fast responses, super fast production, and quality products at a great price!

Lenita was absolutely amazing. Extremely helpful and very professional

The helpful service of Aerilla who helped even give suggestions despite it being more work for the provider to ensure I was happy with the product. I highly recommend this service provider!

Kara was wonderful

Eivo was our designer/contact with GS-JJ and always responded to emails within 24hours. We presented him an idea for our design and when we asked for modifications he was always quick and fast in the changes. We had 3 rounds of mock ups from Eivo before a different supplier got back to us with his first mockup. That was the reason we went with Gs-jj, Eivo as quick response and designs.

Process to get a proof of the patch, have them produced and received them was easy and not stressful.

Great customer service Every query was answered with care. Nancy always replied to email queries and helped us at every stage of the process. We're very happy with our enamel badges and are likely to buy more in the not too distant future.

Max was great!

Absolutely loved my experience! The custom patches turned out perfect. The quality was excellent, shipping was fast, and they paid close attention to every detail. Huge thanks to Liz, my sales coordinator, for her friendly support and great communication. Highly recommend!

Mario's Service

Liz was a great help and the pins GS-JJ made are fantastic, exactly what we were looking for.  Thank you so much for your help and the speed of delivery. I highly recommend this company and Liz is a fantastic asset to them.

GS-JJ.com did an excellent job designing our custom spinner science fair pin for our student scientists & engineers to exchange with other students from 70 countries while at the Regeneron International Science and Engineering Fair 2025. Christina was our company representative who handled all communication for customization of our logo onto a spinner pin, expediting manufacturing and delivery too. We are extremely pleased with the outcome and especially with Christina's expert handling of our needs.

I loved my pens. This is my 2nd purchase and Max was nothing short of amazing.

Max was very helpful throughout our design process.

Very Happy with product Nancy was very helpful and very friendly and very patient with me to making sure that my designs was perfect.

Amazing product, better than expected.

Great product with a team who is invested in the look of the final product. As a hobbyist illustrator and graphic designer I didn't know what I was getting into with these challenge coins. I'm very thankful to the team who helped me along the way and were able to achieve a beautiful product! It was a pleasure to work with this team.

The website was very easy to place my order, the low minimum was perfect for my event, and Kara was fast at responding and always very helpful!
