Query: Very sturdy flask

I bought this to replace a smaller flask, and I'm thrilled with this purchase. I also purchased aFunnel for Flask Filling - Stainless Steel with Polished Finishto go along with it, as if I don't use the funnel, then liquid will go all over.I like how plain and simple this is. It also carries a lot, is quiet, and is unobtrusive.When pouring, I tried to squeeze it together, to get the liquid to go out faster, but it's too sturdy, it won't squeeze together.Pros:+Stainless steel, because stainless steel is just cool.+Very solid, can't use it as a squeezy bottle.+Very solid latch and professional-looking seal+Relatively large flask, it looks tall+Holds 8 ounces, which is one cup, or 235 ml, or a third of a fifth.Cons:-Doesn't balance very well. It might be easily tipped over.
