All products are guaranteed to be 100% authentic. They are stored in pet free and smoke free environment.All Swarovski items have Swarovski blue tag by default unless it is specified in the note. The O in North Face Tag was marked black to indicate this. The pictures might not reflect the true color due to lighting. Quite often, dark blue comes out like black. The color will be indicated in the listing title and description. I do not offer return so I can offer lower price. But I do stand by my product.
