Product leaks into the cap
Size: 3.4 Fl Oz (Pack of 1), Size: 3.4 Fl Oz (Pack of 1)
The packaging appears to be defective and potentially tampered with. Specifically, the nozzle is a different color from the rest of the tube—one that is not consistent with the brand’s standard packaging (I am familiar with this brand and have purchased it before). Additionally, the cap does not close properly, causing the product to leak into the lid and resulting in unnecessary waste.
This raises serious concerns about the product’s authenticity, quality control, and whether it may have been previously opened or altered.
