Choosing an Ideus straw tumbler

This is the corner of the range with the strongest claims. The straw tumblers are the pieces whose listings say the lid is leak-proof and that you can put the drink in a bag, and that sentence is not made anywhere else on this site.

They are also the pieces that suit iced drinks best, which is the point of a straw: you drink without tipping the vessel, so the ice stays where it is and the lid stays closed. Two sizes come with a handle, which makes them cup-holder awkward and desk-friendly, the usual trade.
