empty bottles for massage oils or lotion work great [SEP] it is a simple product just an empty bottle with a pump on top that fits massage belts but this is very well made and i appreciate the quality and valuethe listing says it is designed specifically to work with creams and lotions but fyi i am finding that it is great for massage oil as well it has not leaked and has a good seal perfect amount of tension resistance when pushing down the pump in my opinion i would recommend this product by made by body linen packaged well protected from damage effectively arrived so clean and new looking they are new in plastic bag i almost felt like it was silly that i cleaned the two bottles i bought before use a habit because these things looked sterilized and perfect alreadynothing to complain about and happy to find this item and have it work so flawlessly
