## Description

Do you take your thermos or flask when you&#x2019;re on the go? Would you like to enjoy your morning coffee&#x2026;and have it still be hot when you want it?   Our stainless steel vacuum-insulated flask is just what you need! You may be wondering&#x2026;What is a vacuum flask? It&#x2019;s a thermos that has two layers from which the air has been evacuated in a nearly gas tight enclosure. This provides a better insulation performance than conventional insulation materials. Often the inner layer is glass, which is notorious for breaking if you ever drop your thermos! Our vacuum flask is stainless steel on both the outside layer and the inside layer! It&#x2019;s NOT going to break! We designed a vacuum flask that&#x2019;s going to last. It&#x2019;s strong, corrosion-resistant stainless steel, fashioned in a streamlined shape that&#x2019;s lightweight and fits in most car cup holders for convenient transporting. It will keep your hot beverages hot or cold beverages chilled for hours. It holds 500ml (16.9 oz.) of your favorite beverage, from hot coffee to a frosty smoothie in the morning, or a batch of your favorite cocktail for the tailgate party! It&#x2019;s completely leak-proof when closed, and you can just open the spout and pour without removing the stopper. The stainless cap has the same sleek lines as the flask, and is also a drinking cup! This is a great gift idea for family and friends, and would be easy to have engraved for making personalized groomsmen gifts as well! Click &#x201C;Add to Cart&#x201D; right now and get your stainless steel flask ordered today!  For best results, please read detailed instructions.

## Customer Reviews

### ⭐ Unfortunately not as good as it looks
            
*by P***L on April 3, 2016*

This flask looks much better than it unfortunately turned out to be. I followed the care instructions precisely but after just one use, rust began to develop on the inside of the flask wherever there were defects in the metal. If you look at the attached photos, you can see that rust developed in a lot of places.I should give credit to the seller for getting back to me quickly after I reached out to them. They sent out a replacement immediately. Unfortunately, the replacement unit had the exact same issue.I would suggest spending a little bit more and getting a Thermos or a WaterVault which I ended up doing. I have no rust issue with either of those.
  

### ⭐ Don't
            
*by F***O on May 26, 2016*

This isn't a great thermos.  As soon as you fill it with hot liquid it becomes hot to the touch on the outside.  So it is clearly not insulating the contents. I think it is a Chinese knock off.  The one I got has NO markings on it at all.
  

### ⭐ this is crap
            
*by A***L on February 23, 2018*

The inner cap/lid is a complicated assembly intended to allow pouring and resealing of the flask by pressing a button in the middle of the cap. This device fell apart into six pieces after a couple of weeks of use, and could not be reassembled. I suppose something broke, or came unglued. The flask is now worthless. Thank you, China.
