Testers are meant for people to try the fragrance out before they buy it. Stores cannot sell tester fragrances directly to customers, so quite often, stores have too many testers so they sell them to 3rd party wholesalers or overstock/online stores.
There is no difference in the juice between a tester bottle and a real bottle. The reason why tester bottles are cheaper is because tester bottles usually come without a cap. Also, testers come in a plain white box without any of the art or graphics.
We guarantee that our Tester lines are all 100% ORIGINAL, FRESH & have NEVER EVER been opened, or used in any shop and have no defects on the bottle.
