Made from exceptionally durable hard white plastic that doesn't bend.
Note: At 2.75 x 4 inches, it's more square than 4x6, so you'll have to be aware of cropping to make sure you don't lose an important part of your photo. Also, there is a hole in the plastic (see pictures on left), so please realize that part of your image will not appear on the tag.
Unfortunately, it doesn't provide a slot for a business card. Color reproduction is nearly as accurate as on photographic prints.
