I don’t know if you’ve noticed this, but conventional ice cubes simply will not fit inside most water bottles. That crucial flaw in your typical ice cube’s design was noticed by the people at Progressive International, who have introduced Ice Sticks in order to correct it.
True to its name, ice made in an Ice Stick Ice Tray is a slender stick that can fit into any water bottle, which could make the difference between an ice cold refreshment and a lukewarm spit take on a hot day.
Available in blue and aqua, the Ice Sticks Ice Tray can be purchased from Progressive International’s Amazon shop here for under $8.
