Tupperware products are very good in quality . I have their tiffins and bottles . Bottles are same as it was 2 years ago .The color is same .The plastic is of very nice and thick quality. It has fell off so so many times . But nothing has happened not even a scratch. It us way better than bottles from other brands . Except for the fact it is little pricy. But nice quality and durability . You can literally use it for many years.
