I would like to share my feelings about tupperware products. The company prodcing good quality of products. I love to use these products. I have compared tupperware and plastic products. Tupperware products durability and easy of use is excellent when I compared with plastic. Especially these are very good for carraige hot food items. For example I used to drink warm water by filling my bottle from filter. I would sugget to all if any body wants go for it. I can give 4 out of 5 rating. Very good durability easy of access. Easy to clean. Product service is very good compared to plastic. Thankyou tupperware.
