about 5 years ago, i bought my eldest a 750ml classic vacuum water bottle. as an energetic grade schooler, this bottle survived countless drop
tests, roll tests (school ramp), and even bumps from lobby handrails/walls/doors in school.. i was very impressed - built like a tank indeed! i no longer had to buy water bottles for my kids every school year!.. my youngest gradeschooler now uses this water bottle.. my eldest already needs a bigger one so i bought my kid this jug tumbler.. there’s no doubt, this jug will survive many years in school too!
