The 2-in-1 cap features a standard screw head to dispense the main formula of the tube in a traditional way. It also presented a compartment where solid formulas can be poured in for a 2nd step of the care routine or for a complementary product.
This very convenient tube allows the consumer to have 2 formulas in the pack. Standard lotions come out the tube, while solid formulas are contained in the cap and can be seen through the transparent over cap.
