Review on 🍼 A5 memobottle - Compact Flat Water Bottle for On-the-Go, BPA Free, 750ml Capacity by Mark Estrada

Of course it fits in books, eliminating the need for a bottle rack, but at what price? They had to sand down the structure to prevent the bottle from being crushed by your other books, so they made the plastic thicker, making the bottle bulkier and heavier. While it wouldn't matter if you put it on a shelf, it seriously hinders the portability of the bottle in a backpack where space and weight constraints are paramount. Good build quality but not the bill for something you'll want to carry around all the time.
