We used the 1" x 1" labels to perfectly design and craft labels for our car diffusers that we sell in-store and online.
They were used to brand and identify our products, they were easy to use and were created through an EPSON Eco Tank Printer.
Make sure you are using a software like Adobe Acrobat to properly get the margins and everything correct, trial and error will be the best solution to any problem and don't give up because it is possible to create high-quality labels from home.
