Photo Luggage Tags Made from exceptionally durable hard white plastic that doesn't bend. Note:   At 2.75 x 4 inches, it's more rectangular than 4x6, so you'll have to be aware of cropping to make sure you don't lose an important part of your photo. It requires a minimum of 350x480 pixels. Unfortunately, it doesn't provide a slot for a business card. Color reproduction is not as accurate as on photographic prints.
