4 Pack Mini Water Bottles, 4.4 oz Small Stainless Steel Insulated Bottle, Leak Proof Water Bottle Keeps Drinks Hot and Cold, Portable Purse Water Bottle for Sports Travel, Silver

Very happy with these bottles. We intend to use them when traveling, or when taking food to visit others. They are the perfect size for salad dressings! We are using one just for taking cream for our coffee when we go on the road as they are just the right size for what two of us use in our morning coffee -- two 16 ounce cups of coffee each. We have tested for water-tightness and they do not leak. The stainless steel is of the quality you would expect in a small thermos bottle. The lid seal gaskets seem a little light-weight for the application, and while they are holding a seal now, I am not sure how they will hold up over time. Overall quality is similar to other bottles we have and the price is very good. A four-pack is the perfect quantity for what we use them for.

I didn’t know if I would like these water bottles due to their size. Turns out these boules com in very handy. These bottles are small enough to slip into a jacket pocket or a purse. The thermo efficiency of these bottles is also very good. I filled a bottle with hot water (190F degrees), two hours later the water temperature was 150F degrees. 12 hours later the temperature was still at 95F degrees. Which was surprising. But what about the size? For me, this water bottle is the perfect size for those times when I need to take water with me, but don’t want to carry a full sized water bottle. My wife can carry one in her purse without much hassle. And though I will use these bottles to carry cold water. I had an opportunity, a need rather, to fill it with hot water for a medical reason. Even though these bottles are small, they held enough hot water and kept it hot enough to be useful for the entire afternoon. Again, these water bottles are very handy.
