What is tester cologne?

Tester cologne refers to a version of a fragrance that is used in stores for demonstration purposes. These are the bottles that sit on shelves that customers can try before they buy. They are often sold at a cheaper price than the regular bottle because they do not have a decorative box or packaging. Tester colognes typically come in plain or unmarked bottles with a simple label. They are the same formula and concentration as the regular cologne but are marked as testers to distinguish them from the regular product. Tester colognes are a popular option for customers who want to try a product before committing to the full size or for those who just want a cheaper alternative.
