STANLEY 40 oz Rose Quartz Flip Straw Tumblers

Although this is a larger form factor, it is a very good water delivery system. This has been used in 90° plus weather and it still keeps the ice from melting in my drink all day and even to the next morning. It's a great grab and go for a worksite; it is not tippy, which is why I chose this form. Easy to clean. Not necessarily for cars unless you have a giant cupholder. Doesn't leak if tipped over so you could keep it on your car seat. Excellent sturdy handle. I expect this to last forever! Highly recommended.
