I have always opted for steel flasks over other regular water containers like bottles or sippers. After all, they are sustainable and environment friendly. I recently got this Duo Tup steel flask from Tupperware. I have been using it for a while now and here is my detailed review of the product.

My Experience

Staying hydrated is so important and that's one lesson I learned during the lockdown period. One of the reasons why I ordered this steel flask during the winter season is that I wanted to drink lots of warm water through the day. Before starting my work, I always fill the flask with hot water and keep sipping it through the day. 

Now that summers are around the corner, I still wish to stick to warm water as it helps me stay fit so this flask is my bestie now! I always keep it handy. On days I am heading for a casual outing with friends, I keep it in my handbag. I love that it easily fits in there and is not very heavy too. Also, I don't have to worry about the water spilling in the bag as it comes with a silicon gasket which makes the bottle liquid tight.

On days I am out for a long drive with friends or family, I carry two to three cups of homemade tea in this flask as it remains hot for a long time (approximately 6 hours) and helps us all enjoy some refreshing tea just anytime, anywhere! 

For those who crave cold water during these hot summers, I think this flask can be a great pick. The bottle keeps the beverages cold for up to 12 hours.

Talking about the look of the bottle, it has a very trendy, shimmery design. The bottle has a wide mouth which makes it easier for me to pour anything. Also, did I tell you the bottle has a removable anti-skid rim at the bottom? That further makes the flask so easy to use!
