This set of Tupperware water bottles is made of quality polypropylene that is strong and durable. Also, as polypropylene does not affect the contents of the bottle, even on storage over a long span, these fridge bottles are more hygienic and also sturdier. The bottles can be availed in different colours and come with a matt finish. Each bottle has a capacity of 500 ml and has a make that fits into the refrigerator very easily. Moreover, with the easy-to-open flip-top caps, water can be poured easily without having to open the lid.
