Perfect Teacher Water Cup for Long School Days
Size: 40 Ounces, Color: Rose Quartz 2.0
As a teacher, I carry this with me constantly, and it’s honestly been one of my most-used purchases. The 40 oz size is great because I can fill it once in the morning and not constantly worry about refilling it throughout the school day.
It keeps water cold for hours, even when it’s sitting in my classroom all day, and the handle makes it much easier to carry along with everything else teachers somehow end up holding. I also like that it fits in my car cup holder despite being large.
The straw lid is convenient for quick sips during class, and the Rose Quartz color is really pretty without being too flashy. The cup feels sturdy and well made, and it’s held up well to daily use.
The only downside is that when completely full, it can feel a little heavy, but that’s expected with a large stainless steel tumbler. Overall though, it’s been incredibly practical for staying hydrated during busy teaching days.
Definitely worth it if you’re someone who’s constantly on the go and wants cold water all day.
