I gifted this set to my husband and he simply loved it. He is a big fan of Kama products after the use of a foam based face wash so i thought gifting range of products would be a good idea and the he simply loved them. He tried lip balm, face wash from the set till now and they are wonderful. Facewash is working like a wonder on his face and it helps him to fight pimples with his regular gym routine
