The big ones are called Polar bottles and are from the Container Store. They are 24oz and are freezer and dishwasher safe. The double wall construction provides insulation. And the best thing: they are made in the USA!!! You can check them out HERE.
The small bottles are made by Sistema in New Zealand (no China, yippee!) and hold about 8oz. They have a pop-up top so when you twist the bottle, the blue or lime green part pops out. Easy enough to open and close. Also from the Container Store.
I also invested in Name Bubbles, that are waterproof and dishwasher safe to mark the new purchases.
Next time lunch menus!
