Well, let me clarify something about that type of question.
First, no one has any right to claim copyright for an uploaded design that you bought from us. Our license doesn't allow such claims. Please see our license terms here
You can learn more about this here.
Secondly, we sell a customizable design template which means you are able to edit text, colors, shapes, fonts, and some other stuff as specified by your needs. We always recommend you do some basic editing in these designs before uploading them on the POD site.
You can edit our design by following our help center article here. Some videos are also available on the download portal.
We have no objection on using these designs same as it is. Moreover, we are not responsible for anything unpleasant. Since we offer editable files with step-by-step editing instructions.
Our goal is help you to save your hours of hours time to find and create new ideas and designs for your print-on-demand business. tshirtbundles.com is a design library where you can discover thousands of design ideas and create wonderful designs within a few minutes using our premade customizable template.
