The Chemical & Engineering News Magazine has released its 2022 gift guide for the holiday season, which includes The Calculated Chemist's flask soap dispenser.
I love my flask vessel! It is sleek, practical for regular hydration, and the workmanship is of the highest standard. Initially I was on the fence about getting it engraved, and I am delighted that I did, as it adds that personal touch of class ; )
I love this tumbler! The only reason I'm deducting a star is because the spout is always open. So, despite the lid being on, you can still spill on yourself. Besides that, I love the product.
