Legitimate perfumes typically have cellophane tightly wrapped around the boxes. See if the cellophane is loosely or poorly wrapped, to the point where it is moving around the box. Improperly wrapped cellophane is a telltale sign of counterfeit perfumes. You can often discern the authenticity of a perfume merely by inspecting the right parts of the box. Before opening your perfume, carefully examine the box for any signs of unprofessional packaging and design.  Examine the text on the back of the packaging. Check for grammatical errors, misspellings, poorly laid out information, etc. Real packaging for a real perfume should ideally be grammatically correct. Spelling or grammar mistakes can indicate the mark of a counterfeit.   Real packaging is made from high quality paperboard. Boxes made from thin, flimsy material are often counterfeit. Look for the barcode on the packaging. The barcode must be placed on the lowest back portion and not on the sides. Check to see if there is any excess glue or tape. Real perfume shouldn’t have any messy glue residue or extra tape inside or outside the container. Authentic perfume will have all of these numbers on the packaging, which can then be used to independently verify its authenticity. Consult the manufacturer to see whether the numbers match with their production numbering. Real perfumes have smooth bottle containers while imitation bottles are often a bit rough and are usually poorly made, sometimes constructed with plastic. Quality perfume bottles have tight fitting caps that are spill-proof. Be aware that designer perfume labels treat the bottle as part of the perfume experience, so the bottle should be of a superior quality
