Tronix Imaging 3R Digital Printing - EVO Prints 3.5 x 5 inches Photo Print - Water Resistant and Long Lasting Print │3R , 4R , 5R / A5 , 8R / A4 │

To get 3R-sized prints, you would need to have access to a digital printer or visit a printing service that offers photo printing options. You can either print the photos yourself if you have a compatible printer and photo paper, or you can upload your digital images to a printing service's website or visit a physical store with your digital files.

Once you have selected the desired photos and specified the quantity and size (in this case, 3R), the printing service will process your order and print the images onto 3R-sized photo paper.

Remember, it's always a good idea to check with the specific printing service for their available print sizes, pricing, and any specific requirements they may have for submitting digital files.
