Testers may come in a variety sizes and forms of packing - some come with simple white or brown box with or without a cap and may be labeled "Demonstration" or "Tester" the quality of the perfumes themselves are not affected at all and are the same as the one in retail fancy box . All testers are sold unused, with the entire original quantity in the container. If you're purchasing for yourself, testers are a great way for you to get perfume for better discount but may not be appropriate for gift.
