It's Melissa from Contrado here. How is your business going? I see your question hasn't been answered so I hope I can help!
Contrado is a print-on-demand company and we offer custom labels and tags for your products. You can find all of our label accessories here: contrado.com/personalized-labels
Additionally, you can customize many of our apparel pieces and there is a space for you to add a label directly onto the garment.
Let me know if there's anything else I can help with 🙂
